For successful system administration, you need something beyond the necessary technical skills. The following is a list of five slightly non-technical capacities that should be developed to turn into the best system admin ever.

1. Monitor, measure, and record.
Indeed, you know what the swap use is today in light because there's an issue with the disks thrashing and it's making the server go slow. However, your clients are complaining to the management that it's an ongoing issue and now the management is asking you for an explanation. What, you haven't been reporting this, so it's now your word against Sales and Marketing? Think about who wins that argument of course? You're liable for the system, so they will make this your concern.
So get/build/purchase a system to monitor, measure, and record that data so you can build beautiful slides for fund next time you have to request hardware upgrades or to prove that the issues are caused by terrible software rather than your perfectly working servers. Regardless of whether you are simply running a single server for a business, a customer, or even yourself, its good data to have for some unexpected reason sometime.
A shortlist of things to start monitoring/recording/outlining/graphing:
When you have consistent data, you'll begin seeing examples and can search for things strange. It's also useful for associating data to behaviors when you're troubleshooting issues and aren't sure where to begin.
2. Create project management habits.
In any event, for small, one-person undertakings. Review a small scope of work, compose prerequisites, get sign-off from partners on their expectations, plan a schedule, and record your activities. Write up a postmortem report toward the end. Regardless of whether it's only for yourself. It doesn't need to be fancy, and it surely doesn't need to be formal PMBoK activities.
It might appear to be bureaucratically managing with all that paper and it might appear as though you're spending more time in paperwork than sysadminning, however, it helps keep you organized when your supervisor hands you random high-need task that strays you from your assignment. It's also helpful when you build a new system and clients complain that it doesn't do what they needed it to do. See? You got their approval on the requirements document in that spot…
Regardless of whether it's only for yourself, one day you'll ask yourself, "now why on earth did I install Acme:: Phlegethoth on this server? Oh yeah, it was for that weird cooperative who needs it for their application code… "
3. Build up a system for everyday work.
Once more, this may appear to be bureaucratic, however, if you go through your days simply "doing stuff" without a schedule, you may find that it is hard to explain to your supervisor one week from now precisely what you've been doing with your time. I've become a fan of Kanban sheets recently because it's a visual device that your chief (or any individual who appoints you work) can associate with. Suppose I have three things I plan to work on today that should fill up my 8 hours.
"Goodness, you need me to work on this other thing? Yes, sir! Here is the thing that I planned to work on today. Which one would it be advisable for me to deprioritize for this one? Gracious, so it's a higher priority than this one, yet not as significant as these two? That is fine, I can re-queue that lower priority one and find time for it later." This helps set expectations. I am aware of one graphic designer who utilized it to coordinate her work between three competing project managers. If one requested that she organize something, she'd give him her board and send him to the next project managers to negotiate the conflict and coordinate their deadlines. Regardless of whether nobody else takes a look at your board but you, it assists with keeping you organized.
4. Develop communications skills (sales, presentation, and so forth).
It took me some time to really understand why this is significant. Truly, today you just won't sit in a server room, keep things running, and take a look at Lolcats. In any case, tomorrow, you may have others helping (or working for) you. You should have the option to convey expectations. You have to propose and advocate your ideas (extraordinary thoughts never remain individually merit except if and until they are appropriately communicated), to your friends or to the management. Possibly you have to persuade somebody that they have to redesign the webserver. Possibly you have to clarify your new
5. Begin planning for "what if" scenarios.
Your servers will crash. Your servers will be hax0r3d. Your backups will be corrupted. So start figuring out how to respond when that occurs. One of the unhappiest days of my life was the point at which my own server was r00t3d. I did quite a few things, yet the attackers were more devoted to getting in than I was in keeping them out. How would you remove a rootkit after it's found? I didn't know at that point since I never asked the question (remember? I thought I did quite a few things to prevent it in any case). Server suggestion that will fix every one of their issues. Perhaps you have to persuade the developer that his code is truly causing those memory leaks, however, you have to introduce it in a non-accusatory manner. I'm personally a big fan of Toastmasters for this, as it's the cheapest and effective approach to improving your capacity to communicate.
You can bet I certainly know now! What happens when the server drops off the network due to a power outage, and now it's saying "kernel not found"? What happens when your customer or internal client requests you to reestablish a backup, and the backup is ruined?
You may not find all the solutions to these until you really experience them directly, however, it's smarter to begin asking the questions now and not when you have angry individuals yelling at you. Additionally, when you begin asking the questions, you can start setting up "self-training" scenarios to test it.
Set up a test box and remove the kernel. Check whether you can get it back to operational. Try to get somebody to install a rootkit on it or at least do a bunch of stuff that you need to troubleshoot and fix. By asking these questions now, you'll be in a vastly improved situation to manage them later.

Regardless of whether you are simply running a single server for a business, a customer, or even yourself, its good data to have for some unexpected reason sometime.
A shortlist of things to start monitoring/recording/outlining/graphing:
- Load average
- Memory usage
- Disk I/O (transactions every second)
- Network throughput (in Mbits/sec)
- Network throughput per virtual host/site
- Transfer (in GB/month)
- Transfer per virtual host
- Disk storage (month to month in GB) and also every day rolling average if files are uploaded and erased consistently)
- Average response time of test URI under your control (in milliseconds)
- Average response time of a PHP (or Ruby/Python/and so forth.) page under your control that doesn't change. Testing real website pages give you a consistent standard that you can use to limit the issue to the server, the OS, or the web code itself.
- SSH logins per day/month by client and IP address
- Anything you feel is vital or will get questions on later
When you have consistent data, you'll begin seeing examples and can search for things strange. It's also useful for associating data to behaviors when you're troubleshooting issues and aren't sure where to begin.
