A beautiful road is a beautiful friend; you never get bored with it!

For someone who doesn't have the key, the door becomes a wall; for someone who has the key, there is no door!

Much sooner than we think, comes the end! Science is the only master who can change this.

What is better than a peaceful man? What is worse than an aggressive man?

Leave your fears; you will then have a better life!

The probability that a genius can do stupid things is much higher than the probability that a stupid can do genius things.

Bridge shortens the roads; wisdom does the same!
