One of the major requirements of success is perseverance. You have to be able to focus on your goals, dare to try things that are new and be willing to fail without giving up.
I think the major secret of success is handling adversity, which seems to be an everyday occurrence. Losers often see adversity as devastation. Winners see it as a way to learn and improve.
The lesson here is that you can’t be a winner unless you handle adversity with perseverance. Throughout history our greatest leaders are those who persevered when others would have given up.
