It shows

People can tell how much I love myself, by looking at what I say and most importantly, what I do. Self-love shows like a white spot on a dark garment. How well you take care of yourself, body and mind; your physique, posture, mental attitude, everything about you says something about how much you love yourself.

Exercise self-love, aware of the fact that it shows to people. Enough self-love can make your life more optimistic, satisfying and admirable. Too much of it can have negative effects too: selfishness and conceit, to name a few.

People can be your mirror too, in that respect. A person with a healthy self-love is attractive.
