To know oneself, one should assert oneself.

What you do today can improve all your tomorrows.

I can, therefore I am.

If you think you can do it, you can.

The dog that trots about finds a bone.

Things do not happen. Things are made to happen.

It's always too early to quit.

Without hard work, nothing grows but weeds.

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