What you do today can improve all your tomorrows.

It's always too early to quit.

Never complain and never explain.

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

Problems are not stop signs, they are guidelines.

Begin to be now what you will be hereafter.

Things do not happen. Things are made to happen.

To know oneself, one should assert oneself.

By failing to prepare, you are preparing to fail.
