Persistence

"I want to remind you that success in life is based on hard slogging. There will be periods when discouragement is great and upsetting, and the antidote for this is calmness and fortitude and a modest yet firm belief in your competence. Be sure that your priorities are in order so that you can proceed in a logical manner, and be ever mindful that notion will take the place of persistence."

-- Walter Annenberg
