Most beneficial thing is to choose a more minimalist lifestyle. Buy only if you need it, use only if you must and discard only if you absolutely have to. These principles can be applied to pretty much everything, from eating at a restaurant to buying clothes to using technology.
Just go and do whatever you feel like. Eventually you will set up a routine and might even get into science based optimisations. Don’t overthink it. Doing anything is better than doing nothing.
lol. I meant it in the medical sense
