here's something i think about a lot when it comes to taking profit, whether i should reinvest money i've previously taken out, or anything else

if i'm good enough to make money with a bag of X size, i should be good enough to make money with a bag of Y size

so i should be able to get back where I was if I take this money out - if not, then I probably would have lost more money anyway

It's hard to go broke taking profits. People get too greedy and hung up on opportunity cost.

Probably not well accepted by some but this is my golden rule. Once you take a percentage out, that stays out. No matter what.
This way it's easier for me to hold the rest.
