Many think that the short term gain will be worth the long term pain, but it isn't.in addition, using steriods is cheating, and there is nothing worse in sports than a cheater. Don't do it.”

                                      -  George Mitchell

What i understand about this quote is that it's when you cheat  you only feel good for a short while, and then in the long term you'll feel the pain and how much you regret it. So it’s best not to cheat and do the thing correctly without cheating, without choosing the wrong. The worst part in sports is to find out the winner cheated to get to success. An that's really shameful. It's always best to choose the right, and have pride over it, than to choose the wrong and have long guilt when you cheated.
