What combinations get the best results?
You want to have perseverance and grit, when can you best train for those? Make it hard on yourself, train under harder than usual conditions and then when the time comes to perform, it feels easy. That has been done by coaches for many years. Seems that the same idea is used for Flow.
First, choose a weakness to work on. Put it at the end of the day, so you are already tired. Exhaust yourself before you start addressing the weakness.
Use a few of your active recovery periods overlapping- the sauna and bath, to practice mindfulness. Combine your workouts and get more benefit, but make certain you are doing them well.
Try to make books your primary information source- when you’re loading the pattern recognition system, you can’t match the data density with any other material.
Use “the MacGyver method” before you enter your release/mindfulness practice. That way the practice does double-duty.
While you’re still working way through passion, play at the intersection of curiosity as a time to load up pattern recognition with the information it needs to find connections between ideas.
Always layer flow triggers into every activity. Make novelty, complexity, and unpredictability your good friends. Make sure that items on your clear goals list sit in that challenge-skills sweet spot. Find a Feedback buddy. Practice taking safe risks and repeat.
