Good question. I'm always of the mind of if im not good at something I'll go learn it, as long as it's not too far from my core disciplines.
Personally I usually get bored. Problem is I don't have the cash to outsource the simple stuff lol.
One thing I'm trying to do is do something with a project everyday, even if it's just turning it on and changing a single line or code or even a single attribute. It helps you get into the routine of doing something everyday to move the project forward. Apparently if you do it for 21 days in a row then it basically becomes a habbit. (I have yet to reach 21 days).
