Healthy selfishness is a prerequisite for inner comfort.

If we care too much about others, it turns into a problem. By constantly giving in and considering our inner self to be less valuable than others', we erase our personal boundaries and concentrate completely on the needs of others. Swallow resentment and give in, or say "no, that won't do!" and allow ourselves to be HAPPY. Always trying to be "good" is pointless. Sooner or later something can go wrong and you will be certainly blamed and criticized. Living only for someone, you have to ignore your own desires and needs. Remember: sacrificing yourself for others is your own decision.
