If you want to reduce the rats, use the cats! If you want to reduce the fools, use the books!

Every heart has a door; knock it gently! If the door is not opened, leave gently!

You may cross many bridges and you may travel many roads, but you will always carry your own nature with you! Your nature is your shadow!

Biological death is only a mechanical problem, it can be solved and man can live millions of years! Do not believe in life after death! Seek for the life within the life! The medusa of Turritopsis nutricula is biologically immortal and this little creature is a big inspiration for us! He who thinks positively reaches his target!

Tradition kills originality; you keep repeating the same things in tradition! Behave like the sky; always create new and different things; be original!

How much weight you can carry in your mind will determine how far you can go in life!
