The problem with the world is that the intelligent people are full of doubts, while the stupid ones are full of confidence.
It’s not supposed to be easy. Anyone who finds it easy is stupid.
The world is a puzzle, and the pieces are scattered everywhere.
If you are looking for something in your house, and you finally find it, when you’re done with it, don’t put it back where you found it. Put it back where you first looked for it.
