Nothing can be taught, everything has to be learned.

A lesson that is never learned can never be too often taught

There is a similarity between life and school. At school, you are taught a lesson and then given a test. But in life, You learn a lesson from the test ,that life gives you!

Learn the optimum from your everyday classes in the school of life

If we taught children to speak, they'd never learn.

Mistakes are a part of being human. Appreciate your mistakes for what they are: precious life lessons that can only be learned the hard way. Unless it's a fatal mistake, which, at least, others can learn from.
