Everything comes back to the sentence; love yourself and don't care about others. For example, I used to care about everything too much, but not now. Now I'm like this: one person wants to leave; one wants to stay, so stay. Someone said bad things about me behind my back, so tell them; look, I'm never going to become a bad person because of other people's bad words. Just know yourself and believe that emotions are useless. Stick to your sport, your work, yourself, and your life. Focus on yourself.
