LPT: for people with low self-esteem. Be as kind to yourself as you are to the people you love. You wouldn't humiliate them, so don't do it to you. You deserve respect as much as them.

Edit: Given some of the comments, it seems that my message wasn't clear. My point is not to tell people to love themselves, because, indeed, it's not a choice. However, we can choose how we treat people. You can be kind to people you don't like. The same way, you can be kind to yourself even if you don't like yourself. Love and respect are two different things.
