Is there any point in aspiring to become a high stakes pro when the passion for the game is not really there? I was never that guy who REALLY loves the game and I don't remember myself ever playing poker for no financial stake. I somehow managed to get a decent and constant amount of money out of poker in the last 4 years (used to grind 100s spin&gos and then live cash games), but I was never that guy who's so much into the game and who thinks hands and situations all the time. I mean my sole purpose of improving the game is just those extra $$ added to my hourly. Also I'm very bad at remembering hands after each session, so I virtually cannot get any sort of reads on people (might be due to the fact that I rather scroll my phone instead of paying attention to the game). Due to this issue, friends suggested me to approach a more GTO based style, as that would be less mental consuming for someone who's facing my problem.

The thing is that I really adore the life that poker has given me, as I'm currently traveling through Asia, getting decent amounts of money playing around here, but will I ever get to play those stakes that each one of us dream about?

Is this lack of passion a big hold back for getting to that point?

No one can answer whether the trade off is worth it but you. Since this isn't a strat question, I'm going to lock it up. Try Poker Psychology if you want others' answers to your questions, or PG&C or House of Blogs if you're looking to record your journey.
