When you desire to perform at a certain level with someone you measure yourself against, you must first figure out how this became the best standard for you to follow, and what you may have to do to get where they are.
If this person had to lie, cheat and steal to acquire what they have, are you willing to adopt the same behaviors or identify with someone who outwardly appears to be at the same level, but did so through hard work and personal integrity? They may both be packaged differently in perception, but one worked smarter in the long run and the other in a way that will have them looking over their shoulder for years to come.
Whatever choice you make, be sure to consider the long term effects of the standards you set for yourself. Accomplishing a great feat in the wrong way can set you up for future failure.
