ENTPs have an amazing personality--one of my favorites and the only one I'd ever choose for myself. However, there's one thing many of us ENTPs keep saying that's not even supposed to happen to our personality: the mindset that "we can't change." I mean, we're supposed to be the ones who look at the rules and say, "why is it that way?" We look at the pyramids of bodies of those who have failed before us and state, "but I can do it." We can take situations so tangled that others can't see out of and unravel a straight line. We dream what others don't dare to and push ourselves where others won't. So then why on earth would we think just because some personality typology says we're an ENTP that we're a slave to that assessment and to so many of the common demons that come along with the blessing?
So we have some common weaknesses -- that's all they are. They aren't irreparable damages or scars or a cross we have to bear. They're merely common ways we tend to think, common ways we're immature, and common things we have to overcome. You don't like being fickle? Make decisions. You want to do something great? Fantastic. Set a goal and get there. The excuses we make for not going somewhere and not accomplishing the things we start out on are just that--elegantly constructed excuses for failure. That's it. That's all. And I'm terribly guilty of doing this myself.
So let's just man (or woman) up, take responsibility for ourselves, and actually do something. It's not easy, but nothing worth getting ever is. If we want fulfilling lives and success in our endeavors, just do what needs to be done. There's nothing really standing between us and what we want besides ourselves. So just make the decision and go for it.
