I believe that it comes down to developing a routine.
My mind isn't the clearest, although it's more clear now than it has been in the past due to meditation, breathing exercises, cold plunges, etc.
Yet, even without a focus as strong as I'd want it to be, I am able to focus very clearly when trading.
Enough so that I was able to make $755,000 in 2017 with a 95%+ win rate by trading options.
