If you think you can do it, you can.

I can, therefore I am.

Without hard work, nothing grows but weeds.

To know oneself, one should assert oneself.

Begin to be now what you will be hereafter.

Know or listen to those who know.

Be gentle to all and stern with yourself.

What you do today can improve all your tomorrows.

The wise does at once what the fool does at last.
