Great point. I've always said that the danger with thinking you are awesome is that it makes you stop learning.

I used to think I was awesome back when I didn't know anything more than a single language and paradigm. It's only years later by seeing a second language, then a third and by looking at other projects' sources that I realized how silly being awesome really is.

After a decade of writing code, I've reached the point where I learned enough to admit I know next to nothing.
