In all facets of life you will have the opportunity to be offended.
At home, at work, at a show, on a sales call, in traffic, the opportunities are abundant.
But ultimately, you get to decide whether or not you take something personally.
Upon deeper reflection most people will find that there is little to no reason to allow yourself to be offended or even bothered by the actions of others.
Maybe they have a personal issue with the situation at hand that has nothing to do with you.
Maybe they're having a bad day.
Maybe they associate you or your actions with something from their personal life, that makes them unhappy.
The only thing we can be sure of is that most of the time it has nothing to do with you.
So don't take it personal.
Wishing you continued success!
