Sometimes I dream being that productive (although his exercise routine is ridiculously short). But then I also want a social life, I want to party with my friends, I want to meet new people, I want to take holidays, I want to meet women... overall I want to be impulsive sometimes.
Having a routine like is just looking for troubles when you end up breaking it one day.
The first thing is to know the tricks that work to make you effective when you want to get into an effective loop: [The chain system, the pomodoro technique, getting good sleep + eating well + sport, no alcohol] does the trick for me.
The second thing is to learn how to balance those things with a social life, with a good one. And I've yet to read an article about it. Maybe I'll write about it if I find the solution one day.
While sure, my productivity might be better with that kind of routine, I feel like I could be much happier if I followed a more nature routine and go with the flow while following a general outline.
No mention of a significant other, socializing, meals, etc. And only 15 minutes for exercise? Seriously? You get more than that in prison.
