|Oh I do so love a good pun!|
I thought about this and realized this doesn't have to be limited to just your success at work, it's totally true for your health/fitness success as well. In college, I lived with a roommate for 4 years who was a cross country runner in high school. During that time, I ran my first half marathon. Prior to that the most I had ever run was probably 4 miles. But because of the time I spent with her, and the fact that we loved to obnoxiously challenge each other to see who was "tougher", I became a long distance runner. (OK so our drinking contests were the negative version of this but hey, nobody's perfect.)
So if you want to increase your chances of fitness success, spend time with your friends who like to go hiking on a Sunday morning instead of doing sake bombs on a Saturday night. Go out to lunch with your coworker who always has her fridge stocked with fruit instead of a candy jar on her desk. Become BFF's with your trainer, make a skin coat out of them, and assume their identity.
OK just kidding about that last one.
