of course, all this right brain "nonsense" should be safely supressed during middle age and FIRE preparation/execution.
the right hemisphere should be kept carefully chained in the back yard and only let out to run in supervised, fenced dog parks, so to speak.
left hemispheric dominance is associated with social separation, grouchiness, miserliness, linear thinking...all good things when working toward financial independence
however, joy, social connection, empathy, aesthetic sensitivity, is associated with right hemisphere dominance. This can be stimulated with creative activity and the arts, music, charity work or meditation. In my view, learning a musical instrument is "the easy path". (homework - rent the film Harold & Maude)
once financial independence is achieved, that is the moment to take off the psychological straightjacket and run naked in the woods so to speak, or whatever else comes into your head.
There is no longer anyone to answer to or try to impress. The uptight negative personalities in your life will be greatly concerned about your mental health. The more distance you put between yourself and these persons, the better. (save for relationships of duty)
