On: Ask HN: How do I develop focus?

[nont]

I think Jordan Peterson said it that in order to have attention (to me this translates to focus) is to choose your sacrifices.

Your plate is limited, even your brain can deal with just a few things at a time (4 i think from most researches).

I guess you have to mindfully and aggressively say no to certain things or ideas, but that is never easy.
