It's always too early to quit.

If you're going through hell, keep going.

By failing to prepare, you are preparing to fail.

What you do today can improve all your tomorrows.

Leap, and the net will appear.

You never know what motivates you.

Without hard work, nothing grows but weeds.

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

To know oneself, one should assert oneself.
