未来不是命中注定的。没有保证。所以，要主动承担成年人的责任。要有目的性。开始工作。选择你的家庭。做数学题。创造你自己的确定性。不要被你不知道或没做的事情所定义。
The future isn't written in the stars. There are no guarantees. So claim your adulthood. Be intentional. Get to work. Pick your family. Do the math. Make your own certainty. Don't be defined by what you didn't know or didn't do.
The harder you work, the luckier you get.
