I came up with 9 (Good lord do I love that number!) areas that should be researched, soul dug and remembered when playing.
1). Judgements from others are usually inaccurate.
2). Failure to really try is why most do fail.
3). Patience is widely misunderstood.
4). Set a Bankroll and a percentage of the Bankroll for your session Buy-ins and strictly adhere to those.
5). Understand a solid Money Management Method and religiously apply it.
6). Understand your mistakes and learn from them.
7). Little things add up ITLR and otherwise, where you have applied all kinds of losing techniques and thoughts. Change the habit.
Eight). Excuses are lies and laziness, vow not to engage.
9). Understand and appreciate Blood, Sweat and Tears you have given. Avoid them.
