Happiness in this world, when it comes, comes incidentally. Make it the objet of pursuit, and it leads us a wild-goose chase, and is never attained. Follow some other object, and very possibly we may find that we have cought happiness without dreaming of it.
I think that the greatest gift you can give to somebody is your own personal development.
实现明天的唯一限制将是我们今天的疑虑。
Every effort is an investment in the future, a wisdom understood by the wise.
