Be gentle to all and stern with yourself.

You never know what motivates you.

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

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

Know or listen to those who know.

If you're going through hell, keep going.

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

Begin to be now what you will be hereafter.

What you do today can improve all your tomorrows.
