Without hard work, nothing grows but weeds.

It's always too early to quit.

If you're going through hell, keep going.

Begin to be now what you will be hereafter.

Things do not happen. Things are made to happen.

If you think you can do it, you can.

To know oneself, one should assert oneself.

Always desire to learn something useful.

Quality is not an act, it is a habit.
