We had to do a presentation in class and as usual mine was too long and we had to cut it short because class ended. Everyone seemed to appreciate it though, and found it interesting, although they did just want to leave and presumably get on with their business.
Probably just to make me feel better for not being able to finish the topic I was clearly enthused with, they said stuff like "thanks" and "good job" and I had short discussions with a couple people but then just left eventually as another class began to enter.
I have had a similar experience that I wrote about in another thread.
I've written 3 page papers that required 7-10 and have gotten full credit every time. I even did a 10 minute presentation in 2 minutes so that the class wouldn't have to wait because other groups ran over, and the bell rang when I started. The best presentation of the day would get a bag of pretzels as an award, which I ended up getting.
Most people use filler to make a presentation take the required time. Being and effective communicator with less time is a valuable skill.
People are energized by passionate people (just like Steve Jobs or Bill Gates). They are both introverts (debatable?) but their passion is more powerful and charismatic is just another word for passion and enthusiasm.
Afterwards I felt weird and started mumbling to myself while twitching my fingers near my chin (while walking to a destination). I was alone. This has happened before though, usually after I'm embarrassed or disappointed with a performance. There also can be an odd sensation of confidence, if even that. It might be that I'm more in tune with "feelings" or care ("drive"). Before this I could hardly even assert simple things I wanted to do, such as take a picture of something (after I already took one and wanted to take a better one a few moments later).
So at first I had a low monotone voice but put in front of an audience with a topic I know a little about then I could be charismatic, if that. People treat or see me as a normal person. If not fulfilled there's some excess that remained and it was difficult to concentrate on something but went away after a while.
I'm mainly concerned about the mumbling or talking to self part. Does anyone know what that is or have that? If I didn't know any better I'd say it was some type of "schizophrenia" or something.
You may have avoidant personality disorder.

Talking to yourself and hearing voices are two different things. You can see a Dr. and get assessed for Schizophrenia.
To me it sounds like you are experiencing cognitive dissonance. Your internal self is not aligned with your external observations. You have conflicted beliefs and your subconscious is bringing it to your conscious attention for analytical review. As an introvert, you use your internal voice as a dominant validation mechanism (or BS detector). Cognitive dissonance is a result of detecting BS, and it's your bodies natural defense system. You are comparing external stimuli with your most trusted internal advisor.
When this is extreme, and you're very isolated; then you can develop more symptoms of Schizophrenia. People with Schizophrenia have extreme and conflicting beliefs because of trauma and abuse. If you have Schizophrenia and it doesn't negatively affect your life then it isn't a problem. There are many effective Schizophrenics and you wouldn't even know the difference because they would never admit it.
The onset of Schizophrenia can be triggered in your mid-20's by a stressful situation. It can be gradual so if you are concerned you should seek help early so that it doesn't cause relationship problems.
You want to replicate the feeling of confidence because it releases endorphines into your system. This feeling is the same as nervousness, and excitement. Feel good about yourself and reflect on the situation. Positive affirmations are a good way to anchor a feeling to a memory so that you remember it the next time you have the same feeling. It's like flagging to the feeling so that you can understand it better the next time that you experience the same situation by comparison. You can program yourself and others using affirmations and anchoring practically and in a positive way.
Modern therapy techniques are able to treat Schizophrenia successfully. Dialectical Behavior Therapy (DBT) is a great example.
http://www.nami.org/Content/Navigat...pports/Dialectical_Behavior_Therapy_(DBT).htm
Dialectical behavior therapy (DBT) is a specific type of cognitive-behavioral psychotherapy developed in the late 1980s by psychologist Marsha M. Linehan to help better treat borderline personality disorder. Since its development, it has also been used for the treatment of other kinds of mental health disorders.
DBT differs from traditional CBT in its emphasis on validation—a powerful tool whereby the therapist and the patient work on “accepting” uncomfortable thoughts, feelings and behaviors rather than struggling with them. Once an identified thought, emotion or behavior has been validated, the process of change no longer appears impossible, and the goals of gradual transformation become reality. The term dialectics refers to the therapist’s goal of establishing a balance between acceptance and change and effectively integrating these two fundamental principles of successful therapy. DBT also focuses on the development of coping skills—specific behavioral techniques used to combat the disabling symptoms of mental illness.
Note: Uncomfortable beliefs are caused by cognitive dissonance. It has to be a gradual transition and the term "fake it til' you make it" is a valid way of building real confidence. Combined with other techniques you can correct behavioral problems quickly and effectively.
You should read a book called "The Introverts Advantage: How to Thrive in an Extrovert World."

Jesse Eisenberg (INTP)
Actor, dating Mia Wasikowska
Eisenberg: "I can't exist in normal group situations ... where you have to ... jockey for position. I ... just withdraw."
Eisenberg: "[I became an actor through a] series of really weird events. ... I don't think I ever would've tried to be an actor."
Eisenberg: "[When] acting, then there's a prescribed way to behave; whereas in life there's no prescribed way. So acting [is] a comfortable way to get through the day."
Eisenberg: "When I was acting in a play I liked knowing my place - that I was this role, and other people were that role, and we could interact with each other in a way I felt was very clear to me."
Stephen Whitty: "His characters usually have a few things in common. They're extremely bright [and] yet they often seem more than a little confused about what people around them expect, emotionally."
Be true to yourself.
