But do they lead to better outcomes ? My teeth being extra clean is irrelevant to me if I don’t get cavities either way.
Which, afaik, can be prevented by “simply” not eating anything with added sugar. (Not so simple these days unless you cook everything yourself)
4 hours of focused work is generally the maximum, in my opinion. I usually add 4 more hours of low-intensity work on top, to keep up with all the administrative stuff etc.
This is highly dependent on sleeping well and eating healthily, though, and on taking at least one day off per week, if not two.
I’m of the opinion that working hard is foolish, I’m focused on working well. Some days I can do 5 hours, some days I can do 5 minutes. That’s okay, no work is always better than bad work.
