Who seeks shall find.
If you're going through hell, keep going.
What you do today can improve all your tomorrows.
You never know what motivates you.
Begin to be now what you will be hereafter.
Either you run the day or the day runs you.
To be a good loser is to learn how to win.
The secret of getting ahead is getting started.
I can, therefore I am.
Leap, and the net will appear.
I believe you'll develop speed via strength work which includes hill running, either repeats, or running hilly courses as the Kenyans do on a steady basis.
