I asked myself this question.
I thought that I have been through some experiences and I supposed I am able to say what is love.
However I found that I am still learning about love.
I am still reflection about what I did for others.

I learned love is not ”have” but ”give”
I learned love is not pointing the finger to other and say...” you change”
I learned love is not only think about yourself and what is best benefit of you in that relationship
I learned love really is something you will always have him or her in your mind no matter where you go.

Love is having the confidence of yourself. Knowing your own value and stand still for that. In the other side, love is having the confidence of the one you love. You know he is the best and he deserve your love.

This is a lifelong process I think, till we really humble and learn from someone above!
