Drunk, tired, stress would be the most obvious but also most commonly repeated instances that I know of. Basic rule to guide by is dont play while distracted, it's an obvious point against you coming out with winnings. If not able to stick to these rules then be most realistic and reflect your play is not completely serious which is totally fine but at this point do not play with serious money play with practise amounts, learn the game and be casual.
Absolutely fine to refine your play and judge your capabilities on that day, matching it to what size you would bet with. I would call this a strength and resilience by which you are more likely to last long term in gambling as a game without playing yourself.
Good response, all of this can greatly influence the gambler in experiencing failure if he cannot avoid it because drunkenness, fatigue and stress will trigger the gambler mindset and attitude when betting, making it possible for mistakes to occur and betting carelessly.
There are lot of gamblers who experience excessive amounts of failure and one of the reasons for the failure is based on what have mentioned, the mindset of each person in certain conditions can easily be influenced by making mistakes in attitude.
Only thing that is best is to gamble according to abilities and assume that what are betting on is prepared to be lost, this can give feeling of relaxation and can also be more confident in all the results that occur.
If it is lost with money that was prepared to be lost then there will be no anxiety, emotion or ambition in recovering it and this can minimize the occurrence of downturns.
Gambler attitude will always influence the conditions and results that occur, so there must be commitment that is truly made and maintained properly to be in comfortable condition when gambling.
Everything will be easy to learn and understand if have clear thinking and calm attitude.
