Be gentle to all and stern with yourself.

The secret of getting ahead is getting started.

You never know what motivates you.

Begin to be now what you will be hereafter.

It's always too early to quit.

To know oneself, one should assert oneself.

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

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

Things do not happen. Things are made to happen.
