I can, therefore I am.
It's always too early to quit.
Be thine own palace, or the world's thy jail.
To know oneself, one should assert oneself.
Leap, and the net will appear.
If you think you can do it, you can.
If you can dream it, you can do it.
Be gentle to all and stern with yourself.
The dog that trots about finds a bone.
Go for it now. The future is promised to no one.
I can jog, but I can't run. That's hard for me. I like the fact that I can jog for fitness, but to me there's a huge difference between jogging and running.
