To know oneself, one should assert oneself.

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

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

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

Be gentle to all and stern with yourself.

It's always too early to quit.

What you do today can improve all your tomorrows.

Problems are not stop signs, they are guidelines.

Never complain and never explain.
