To know oneself, one should assert oneself.

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

It's always too early to quit.

If you think you can do it, you can.

The secret of getting ahead is getting started.

Problems are not stop signs, they are guidelines.

Well done is better than well said.

What you do today can improve all your tomorrows.

By failing to prepare, you are preparing to fail.
