What you do today can improve all your tomorrows.

You never know what motivates you.

Be gentle to all and stern with yourself.

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

Things do not happen. Things are made to happen.

To know oneself, one should assert oneself.

Problems are not stop signs, they are guidelines.

It's always too early to quit.

Without hard work, nothing grows but weeds.
