Surely you like poker a lot, like most of us, that's why you keep playing, it feels good when you win a tournament or when you reach a final table, when you study, read or watch how other professional players play and then you see that it gives good results, all of that motivates, besides the fact that you meet other people from different parts of the world, with the same taste for poker.
Losing money is part of poker and you have to accept it, even the best players in the world lose money, that's the variance, but with good banking control and adding volume of tournaments you can beat the variance and win money.
