If you think you can do it, you can.

Begin to be now what you will be hereafter.

To know oneself, one should assert oneself.

I can, therefore I am.

If you can dream it, you can do it.

It's always too early to quit.

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.
