The state of your physiology has a much greater impact on your psychology than you think. Most people simply aren’t aware, and continue betting even when they’re out of form.
Betting’s a mental sport, so make sure you train just as hard as the athletes.
I noticed a positive correlation when I became more physically+mentally fit (quitting alcohol)– my cognitive ability wildly benefit.
My thoughts were more clear, emotions extremely stable, and I had a better running streak overall.
