It's important to also continue striving for self-improvement. If you hit a level where you've stopped wanting to learn more and started wanting to simply compare yourself to others, of course you'll look good by comparison - but you're not getting any better.

I started programming using Python. When I started, I wanted to understand the "feel" of Python programming, and that was all my mind could comprehend. Now that I have a decent smattering of Python knowledge, I now realize I don't have a total grasp of transfer protocols and I should probably learn a lower-level C language as well. I started off not knowing one thing, now I have added two more.

I'm still a better programmer, but now I realize I'm clueless about even more stuff than I was before.
