It's always too early to quit.

If you think you can do it, you can.

To know oneself, one should assert oneself.

Go for it now. The future is promised to no one.

Expect problems and eat them for breakfast.

Well done is better than well said.

The most effective way to do it, is to do it.

The wise does at once what the fool does at last.

Know or listen to those who know.
