Are you bored with your job ?

I just read great hackers. I liked the quote:

"The distinguishing feature of nasty little problems is that you don't learn anything from them... It's more a question of self-preservation. Working on nasty little problems makes you stupid. Good hackers avoid it for the same reason models avoid cheeseburgers."

If you look back at what you have done in the past six months, do you believe you have been working on nasty little problems ?
