Be gentle to all and stern with yourself.

You never know what motivates you.

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

It's always too early to quit.

To know oneself, one should assert oneself.

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

Things do not happen. Things are made to happen.

Problems are not stop signs, they are guidelines.

Quality is not an act, it is a habit.
