I think the most important thing in life is self-love, because if you don't have self-love, and respect for everything about your own body, your own soul, your own capsule, then how can you have an authentic relationship with anyone else?
You can tell more about a person by what he says about others than you can by what others say about him.  
运气不好时金子可能变成铁,运气到来时铁也可能变成金。
