Go for it now. The future is promised to no one.
If you think you can do it, you can.
The dog that trots about finds a bone.
After a storm comes a calm.
If you can dream it, you can do it.
Either you run the day or the day runs you.
Be gentle to all and stern with yourself.
Know or listen to those who know.
Be kind whenever possible. It is always possible.
By failing to prepare, you are preparing to fail.
The most useful form of time travel would be to go back a year or two and rectify the mistakes we made.
