Learn to love yourself from the inside-out
In my 4 levels of love, I teach that self-love is the highest level of love. It's a choice you have to make for yourself. No one can make you love yourself. It's a process, but the rewards are worth the work.
You have to do the work every day. It will take discipline. You'll have to set standards you refuse to compromise. Others will see the way you love yourself and treat you accordingly.
