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

It's always too early to quit.

Be gentle to all and stern with yourself.

To know oneself, one should assert oneself.

If you've got a talent, protect it.

The secret of getting ahead is getting started.

Expect problems and eat them for breakfast.

By failing to prepare, you are preparing to fail.

Things do not happen. Things are made to happen.
