You never know what motivates you.
Who seeks shall find.
By failing to prepare, you are preparing to fail.
If you can dream it, you can do it.
To be a good loser is to learn how to win.
Things do not happen. Things are made to happen.
Be kind whenever possible. It is always possible.
Begin to be now what you will be hereafter.
After a storm comes a calm.
Go for it now. The future is promised to no one.
