A lot of us real estate investors and introverted, doesn't mean we can't teach ourselves to become extroverted.

Be careful who you listen to on the internet, public forums have no test required before someone can post something and RE is really for extroverts which means many will post implying expertise while not having a clue.

I've got an excellent extrovert type personality for meeting and befriending people.  

Or, is there anyone out there who has a different style of making it work that doesn't involve being extroverted?

Took me a long time to figure out my inner extrovert.

and 'extrovert yourself' like G.C. says..

While some investors are very extroverted and open to talking about details and specifics of deals, other take a more tight lipped and private approach by keeping it close to the vest. 

Are you an extroverted leader?

What do you do to help yourself when the need arises to be more extroverted?

Very thorough and detail oriented, extroverted-introvert and a bit stubborn at times (see it through!)
