You must love yourself before you love another. By accepting yourself and fully being what you are, your simple presence can make others happy You yourself, as much as anybody in the entire universe, deserve your love & affection.
That is the most common excuse, and the most foolish of all. Love has never prevented a man from following his dreams. If she truly loves you, she will want the best for you.
It's very inconvenient to be loved. Nearly everyone has found that out, sooner or later. The fewer people who love you the less you will have to suffer.
