To know oneself, one should assert oneself.

Things do not happen. Things are made to happen.

Quality is not an act, it is a habit.

Without hard work, nothing grows but weeds.

If you can dream it, you can do it.

It's always too early to quit.

If you're going through hell, keep going.

Begin to be now what you will be hereafter.

I can, therefore I am.
