Live within your income and save so you can invest.Learn what you need to learn.
The most powerful art is the one that doesn’t try to be powerful.
Never forget what you are, for surely the world will not. Make it your strength. Then it can never be your weakness. Armor yourself in it, and it will never be used to hurt you. 
天地和宇宙虽然广阔,但在更大的尺度上也不过是一小部分。
