If you think you can do it, you can.
Go for it now. The future is promised to no one.
Be gentle to all and stern with yourself.
The secret of getting ahead is getting started.
Who seeks shall find.
Be thine own palace, or the world's thy jail.
Do not weep do not wax indignant. Understand.
Begin to be now what you will be hereafter.
Either you run the day or the day runs you.
Be kind whenever possible. It is always possible.
