The title is facetious. You’re actually always supposed to love yourself and doing otherwise creates a shitty world for those around you and yourself. It propagate lies and pain. There is a misconception that pleasure and happiness are rewards, only justified after work and achievement is produced… this is the logic that keeps slaves in place and it should never hold anything higher than the worth of stupid brainwashing and self-silencing propaganda. It is always OK to like yourself. The counter would say that if you always enjoy yourself, you will never get better. Or that you will allow a stupid fate upon yourself and the work you put out to be poor. That is totally untrue. It is not required to hate or anything under loving yourself to change what you produce. That is an emotional state of shock and punishment. It is separate from what you mentally conceive and produce. Create what you love and let go of the mental constructs you hate or you will see more of them.
