It's always too early to quit.
Without hard work, nothing grows but weeds.
After a storm comes a calm.
Things do not happen. Things are made to happen.
Be thine own palace, or the world's thy jail.
You never know what motivates you.
I can, therefore I am.
Begin to be now what you will be hereafter.
Leap, and the net will appear.
The wise does at once what the fool does at last.
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.
