Regarding downswings. You have to develop resilience, period, to face the inevitable.
The fact is downswings will occur.
A while ago I decided no matter if I was up or down, if feasible, I would play some poker everyday. If I had a bad session, but knew I was playing fundamentally well, I allow myself some serious irritation and then learn to let it go quickly.
The flip side being, when I had a great session, to enjoy it but keep my head screwed on because I understood it was down to luck and running well. If my game play did not radically alter from one session to another but results did, then you need to step outside of yourself and gain enough perspective to keep level with the ups and downs.
However (and I know many will always say take a break) I think if you can persevere through a downswing and keep committing to play, you will grow stronger and be able to cope better.
I always remind myself (and the
wsop is underlining it perfectly at the moment) that
all players are going to face bad sessions, bad tourneys and bad events....but every time you see a bracelet winner remember each and every one have endured downswings.
