You like to play poker, it is a vice or it is an opportunity to earn some money and or you think that it is also an opportunity to lose money.
Depends on your skills, bankroll management, discipline and will to study.
Lack of discipline/BM leads to going broke often after some decent scores... or playing under the influence (especially alcohol or cocaine, pot is fine IMO, helps tilt lol).
With no will to study and upgrade youll be mediocre, break even or very small EV+... which leads to great stress if you feel pressure to advance
And if you are not skilled and just not that smart, not much to do really
It's a little bit of everything that you describe. It is a vice, as it includes the opportunity to make some money and therefore people get hooked on it. It's also a chance to lose some money, especially when you do lose, and try to chase your losses by trying to win again...... and simply losing more money as you are focussed on trying to regain your losses rather than trying to play your best poker.
Whatever...as the saying goes.... when the fun stops, STOP.
Don't chase your losses but play each game as an opportunity to play your best poker and enjoy yourself.
