Do not weep do not wax indignant. Understand.
Expect problems and eat them for breakfast.
Leap, and the net will appear.
If you can dream it, you can do it.
What you do today can improve all your tomorrows.
Be gentle to all and stern with yourself.
If you think you can do it, you can.
If you've got a talent, protect it.
Go for it now. The future is promised to no one.
By failing to prepare, you are preparing to fail.
I'm someone who's done the opposite of whatever the received wisdom is, to keep your career going into your 50s.
