I believe that pain is proof of hard work. You will feel satisfied even when you feel tired and are in pain because of your hard work. Not to mention that pain doesn't last forever... Sometimes, [however], pain doesn't really vanish and even if you’re in pain, you have to smile and bear through it. You can only continue challenging yourself like so. Challenges aren't frightening, defeats aren't terrifying either. A principle that I now insist and persist on is the understanding that you can fulfill your dreams when you work hard and don’t give up.
