Until you don't start to help yourself nobody else will.. right ?

So in life, once you become an adult are you supposed to be relying on yourself like help yourself, love yourself, respect yourself first. Are we supposed to consider ourselves as the "top priority" ?

I heard someone said that until you don't start helping yourself and solving your problems nobody else will. If ur goal is to lose weight, someone can advice you on how to lose it but it's your responsibility to take that action.
