It's better to wait for a revolution than to evolve.

You're going to pay a price for every bloody thing you do and everything you don't do. You don't get to choose to not pay a price. You get to choose which poison you're going to take. That's it.

"To understand the world, you must first seek to understand yourself."

Think wrongly, if you please, but in all cases, think for yourself.

要有劳苦的心志，乐观的意趣；宏大的气度，谨慎的言行。
