It seems that a function of Betas is to work together towards realizing some idealistic goal: anything from social and political revolutions to personal dreams. I'm curious about yours and how you are making it happen, please tell me :]
I'll start by giving you two examples of me (an IEI) and my friend Jonas (an EIE): The one thing I want out of life is to have a great family. I'm majoring in mechanical engineering (because having money reduces stress), but I've been taking child psychology courses and of course learning about socionics to educate myself so I can not repeat the mistakes of my parents and understand and value all types of people. I wrote more about it in my introduction post here: link
One of my friend Jonas' things is radical honesty and living out what you believe is right. He is a bohemian anarchist who travels around meeting people and making art. He actually does a comic of his live if you have a few hours to spare. Here is one the he just made about us busking in downtown Nashville link and here is one of those radical honesty things, definitely read the description: link
