You know what's funny? I had the same feeling when I was working with Jason Long who designed the git-scm.com logo [1]. I asked if he could help me design a logo for http://gitignore.io and he came up with an awesome design [2]. It took elements from the original git-scm.com and used them in a creative way to emulate a dot file. I showed it to my friend and he was like "That's so easy to do" and my response was "yeah, but you would have never come up with it 100 designs." My friend didn't refute that.
