I am back again and this time is much more serious

Hello everyone,

i have been playing online poker for 2,5 years. This is the 8th time i went from 300 to several thousands and got busted again. I cant manage my bankroll and control my limit at the table. Probably i am not suitable for this kind of game, i lost alot of money around 30k and lots of time and other opportunities due to this. I still think poker is not pure gambling so i can fix it with time and be successful. Please give me an advice about this. What do u think about my situations?

Best wishes,
