To know oneself, one should assert oneself.

What you do today can improve all your tomorrows.

It's always too early to quit.

Leap, and the net will appear.

Know or listen to those who know.

Without hard work, nothing grows but weeds.

Things do not happen. Things are made to happen.

If you think you can do it, you can.

Begin to be now what you will be hereafter.
