It's always too early to quit.

The secret of getting ahead is getting started.

If you think you can do it, you can.

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

Leap, and the net will appear.

If you can dream it, you can do it.

Know or listen to those who know.

To know oneself, one should assert oneself.

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