I find myself that I play super well for a maximum of 60 to 90 minutes.
Than I start doing silly mistakes and become spewy. As some of you grind 10 h a day :) , like how do you manage to play your A game for so long?
Recently I started imposing myself a rule. Every hand that I play I will take a minimum of 5 seconds to think throw. I also reduced the number of tables from 4 zoom tables to 2.
The results, for me are pretty good so far with the changes, but as you can imagine the numbers of hands I play drop.

Also , before session I listen to some relaxation hypnosis. I think it helps me be in the zone.

Thank you for taking the time to read! All answers are welcome!
