What was the biggest eye-opening disappointment for you when you got out into the “real world”?

For example: for me it was finding out that the world was so much bigger than I imagined, in a way. I grew up in Iota, LA, with 1,000 of the nicest Cajuns God ever put in the bayous. I could write pretty well, play a few musical instruments, drew some cartoons I thought were clever — everybody said “He’s a genius! He’ll be the next Shakespeare, Liberace (God help me), Walt Disney. Then I graduated from high school, got into college and found out pretty quick that there were lots of kids just like me who could do all those things and more, and that I was mediocre at best. Disappointing, but a necessary eye-opener for me.

Anything like that for you?
