where do ideas come from?
I’m always amazed about where I get ideas for new products/management ideas/etc. My fiancee seems to be an incredible source. Not only does she tell me when something sucks, but if I can sell her an idea and she likes it, I know I’m on to something.
Read, listen, chat, socialize, learn. You’ll be surprised where innovation and motivation can come from. Keep that tablet by your bed. You’ll never know when that great idea will come.

Sounds like you’ve got a keeper!
Great point about “keep that tablet by your bed” –
I don’t know if you’ve ever read David Allen’s book Getting Things Done, but a big part of the book is capturing your thoughts.
