If you could construct an alter ego, what would you focus on and whom would you become?

Try not to judge us.

A friend and I decided to toy with the idea of an alter ego. We’re both rather anxious, socially and otherwise, and introverted and were discussing ways to overcome the obstacles set up by those traits. We decided that the alter egos would have to really reach outside of our comfort zones (within reason); primary focus on being confident and outgoing. It was a really light, fun conversation, where we discussed change of appearance, accents, attitudes, interests, etc. So, if you were to make your own sideline persona, whether it be for fun or other reasons, how would you determine what traits to focus on? How much of the real you would you set on the back burner? What other aspects would you consider?

Looking for a vey open conversation. Have fun!
