I am winning player and yet I have a whole host of leaks.

1. Doing other things whilst playing - watching TV, cooking, etc.
2. Not bothering with table selection or sometimes intentionally selecting tables with known sharks.
3. Playing weak tight
4. Playing Axs and then calling when the pot odds are not there
5. Intentionally targeting strong players - this is a stupid ego trip
6. Curiousity - when i can't work out a players betting strategy i will throw away money to find out what they have
7. Playing deceptively against poor players
8. Playing ABC against good players
9. Not bothering to analyse my play enough
10. Complacency
11. Arrogance
12. Greed

Wow it's not a very nice list
