You never know what motivates you.
If you're going through hell, keep going.
If you think you can do it, you can.
Only the educated are free.
I can, therefore I am.
Be kind whenever possible. It is always possible.
Leap, and the net will appear.
It's always too early to quit.
Know or listen to those who know.
Go for it now. The future is promised to no one.
I think it's more important to be fit so that you can be healthy and enjoy activities than it is to have a good body.
