Be kind whenever possible. It is always possible.

You never know what motivates you.

Be gentle to all and stern with yourself.

By failing to prepare, you are preparing to fail.

What you do today can improve all your tomorrows.

Begin to be now what you will be hereafter.

It's always too early to quit.

If you're going through hell, keep going.

Things do not happen. Things are made to happen.
