Be kind whenever possible. It is always possible.
Things do not happen. Things are made to happen.
The dog that trots about finds a bone.
Be thine own palace, or the world's thy jail.
If you think you can do it, you can.
Begin to be now what you will be hereafter.
Always desire to learn something useful.
Leap, and the net will appear.
If you're going through hell, keep going.
Expect problems and eat them for breakfast.
But to me the bottom line is the more education you can give yourself, and the more preparation you can do, the less chance of failing.
