I can, therefore I am.

It's always too early to quit.

Go for it now. The future is promised to no one.

The dog that trots about finds a bone.

What you do today can improve all your tomorrows.

If you've got a talent, protect it.

Things do not happen. Things are made to happen.

To know oneself, one should assert oneself.

If you're going through hell, keep going.
