To have self-respect is to step on the ladder of success.
Our life is like a bird that has a short flight, see, it has spread its wings, now quickly decide its direction.
The higher the aim, the path is equally long and tedious.
The way to better life passes through better books.
Be careful about reading health books. You may die of a misprint.
Most of people are interested in what does not concern them.
Keep your eyes on the stars, and your feet on the ground.
Never explain. Your friends do not need it and your enemies will not believe you anyway.
