Self improvement is ultimately a cope, and it definitely should not be done or practiced simply for foids; no amount of wealthmaxxing or gymmaxxing will ever truly make you attractive to foids, seeing as your subhuman bone structure/facial features/race/height/NT status will always remain...
Though it may help in terms of self defense/comfort/copemaxxing; anything else having to do with "personality" or such is instantly a useless bluepilled cope, considering that your looks and other halos/failos directly influence how foids percieve your personality/how interesting you are.
