Some say focusing on yourself is selfish, it makes sense sometimes,yes,but no. You cannot say that being a coward and settling for a half life,it isn’t a form of being selfish .
Truth is you can’t help others until you help yourself first. Jewish proverb says, first mend yourself then mend others. Your health, your own life, no one can live it for you, only by taking care of yourself first can you take care of others.
