Either you run the day or the day runs you.
Leap, and the net will appear.
Well done is better than well said.
I can, therefore I am.
The dog that trots about finds a bone.
If you've got a talent, protect it.
Without hard work, nothing grows but weeds.
Do not weep do not wax indignant. Understand.
The wise does at once what the fool does at last.
It's always too early to quit.
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.
