He who learns but does not think, is lost! He who thinks but does not learn is in great danger... Men of superior mind busy themselves first getting at the root of things; when they succeed, the right course is open to them.
The superior man is satisfied and composed; the mean man is always full of distress.
True wisdom is knowing what you don't know
Expect much from yourself and little from others and you will avoid incurring resentments
Forget injuries, never forget kindnesses.
When you serve your mother and father it is okay to try to correct them once in a while. But if you see that they are not going to listen to you, keep your respect for them and don't distance yourself from them. Work without complaining.
