I believe that playing poker for long hours can be frustrating, in the long run, the results not gonna be profitable, I myself tried playing poker even for 8-12 hours per day but I did not get a suitable result, some times playing poker online only for a short period of time have a better result for me even 1-2 hours I could make my buy in 7 times more
Well said, I completely agree, and I think that only when you enjoy the game, luck accompanies you.This depends on the individual, but I agree with you that shorter sessions are better.
I play for fun/enjoyment and the little bit of "holiday money" poker provides.
I find that by shifting my mindset towards enjoyment/improvement and away from financial results, I can play these short sessions and not worry about "how much more I could be making." This is often an illusion which leads to "the grind."
I try to avoid the grind.
