The Fire

Do not let your fire go out, spark by irreplaceable spark, in the hopeless swamps of the approximate, the not-quite, the not-yet, the not-at-all. Do not let the hero in your soul perish in lonely frustration for the life you deserved, but have never been able to reach. Check your road and the nature of your battle. The world you desired can be won. It exists, it is real, it is possible, it is yours.

AYN RAND

When I first came across this quote a couple of years ago, it seriously affected me. I come back to it often, and it never fails to inspire.
