It's always too early to quit.
If you can dream it, you can do it.
Wherever you are - be all there.
Go for it now. The future is promised to no one.
Things do not happen. Things are made to happen.
Always desire to learn something useful.
To be a good loser is to learn how to win.
The most effective way to do it, is to do it.
After a storm comes a calm.
Begin to be now what you will be hereafter.
