If you have no destination, you'll never get there.
If you don't look ahead, you'll always be behind.
Decide what your priorities are and how much time you'll spend on them. If you don't, someone else will.
If you want to stay youthful, stay useful.
It doesn't matter if they say you can't do it. It only matters if you say you can't.
What could you accomplish if no one told you it was impossible?
