If mastering Jiu-Jitsu takes a lifetime, we need to think and practice in a ways that rejuvenate the mind and body. Anything less is a degree of psycho.
The challenge is, the more psycho and hyper-competitive a mind is, the harder it is to see a bigger picture.
Racing minds want to race.
When in doubt chill out. Quality over long periods of time over quantity in short bursts.
