I think this is a great subject, I would like to see more ideas. These are activities that I do that still allow me to watch signals.
1. Any pausable game, right now I am playing elder scrolls
2. Lift or do P90X (if you thought getting profitable was a challenge, try P90X
3. Read Fiction, something that gets the other side of the brain working.
4. Read ET, catch up on email, backtest, blah the capitan obvious stuff we all do.
Stuff I would like to do but it takes work to start
1. Learn a new Language
2. Learn to play the guitar
3. Write something longer then 10 pages.
