It's always too early to quit.

By failing to prepare, you are preparing to fail.

Begin to be now what you will be hereafter.

Things do not happen. Things are made to happen.

Without hard work, nothing grows but weeds.

To know oneself, one should assert oneself.

Problems are not stop signs, they are guidelines.

Never complain and never explain.

Be thine own palace, or the world's thy jail.
