"All life is a chance.
So take it!
The person who goes furthest is the one who is willing to do and dare."
-- Dale Carnegie
Check this post out... "There is no Tomorrow." by Nora Dunn.
"If you say you will start something tomorrow, ask yourself why you have to wait."
I really like this paragraph (extracted from the above post)...
"Life Happens while we’re busy making plans. If you wait until tomorrow, you’ll have a whole new set of life circumstances to deal with that will throw you off-course yet again. Don’t be that person who wakes up one day wondering where life went and finds their self in a pickle, or worse – with regrets."
It is written as a financial advice; but I don't see why it can't be applicable in other life aspects.
