You can't change what's going on around you until you start changing what's going on within you.

你给了我最好的我，所以你也会给你最好的你。

The chief beauty about time is that you cannot waste it in advance. The next year, the next day, the next hour are lying ready for you, as perfect, as unspoiled, as if you had never wasted or misapplied a single moment in all your life. You can turn over a new leaf every hour if you choose.

科学不仅仅是寻找答案，更是提出正确的问题。
