To know oneself, one should assert oneself.

The dog that trots about finds a bone.

Never complain and never explain.

It's always too early to quit.

Without hard work, nothing grows but weeds.

The most effective way to do it, is to do it.

What you do today can improve all your tomorrows.

If you think you can do it, you can.

Quality is not an act, it is a habit.
