10 tips to avoid losing

Determine a threshold of loss for yourself, and if you cross it stop playing immediately.

Set aside a certain amount of playing time and be careful not to go over your self-imposed limit. This may also help you to improve the quality of your family life.
Don’t play when you’re tired, upset or under the influence of any substance, licit or illicit.

Spend a few minutes observing the table at which you are going to play. This will give you precious clues about your opponents.

Don’t play at a limit higher than your own. You’re more likely to lose everything than to recover your losses.
Never make a loss against someone into a personal issue. Trying to beat a specific player is the quickest way to lose against everyone.
Don’t play more hands just to catch up. Staying with your usual selection will help you in the long run.

Think about the instances where you negotiated badly and try to understand how you could have done better.
Check to see what your percentage of important wins was. If you are often below 65%, rethink your game
Be objective with yourself, neither too easy nor too hard. Was it un unlucky evening or did you play badly?
