As long as I'm useless, no one can use me. I figured something out today. Some things are hard to understand. Don't ask them why they don't date. Why don't you go to Tsinghua? Don't you want to? Do what you do every day. Work like a slave every day. Don't worry or panic about things you can't solve today. It won't be solved tomorrow anyway, so panicking is pointless. Don't worry about the hardship now; it may be even harder later. Nothing is difficult in the world as long as you're willing to give up. If you can't finish your work, leave it for tomorrow. If you're lucky, you won't have to do it tomorrow. Don't panic. The problem is huge, so panicking is pointless. If I had any ability, I wouldn't be completely incompetent. I don't know what's going on lately. I always feel like I don't know what's going on lately. Instead of wasting energy on hopeless things, it's better to spend your time on things that make you happy. Gold will eventually run out. Don't you agree, buddy?
