Do you think that by being shy and introvert one is at a great disadvantage?

I'm like that; always uneasy (anxious), feels awkward having conversations because I'm not sure that it's the right thing to say. I don't exactly feel lonely, but in a way I do. It's harder for me to open up to people--and in the end it's true that having an inward way of thinking you don't look at the whole circle. I think internally and process my thoughts alone, and don't think about telling other people things; just bits and pieces. I'm struggling right now because I thought that I could handle things alone, like I kept myself that everything was okay and that it was nothing. I want the help, but I've been doing this and hiding it for so long that I keep flipping back and forth to wanting it, to not. Definitely as an introvert and what 'learned behaviors' I've taken in during my life has made it hard to tell people. I definitely feel misunderstood because I feel so self-conscious about what I say that it's kind of just become automatic to make small talk. I've found that it's quite frustrating to be an introvert.

There are two main typesof introverts, those with low self esteem, and those who are otherwise. People with a low self esteem may be at a disadvantage because they tend to hesitate from doing or saying something when they should have done it, thus lsong an opportunity. On the other hand many of them are creative in art and writing because they are able to express themselves without fear. This can be considered an advantage. Many introverts have an analytical mind. Maybe you have noticed that many scientists are shy in public. They prefer to be on their own. In summary I say in general being a shy and introvert person is not a disadvantage.

why share experience or thoughts when all that will happen is an attack on their beliefs. people do not know how to respect beliefs and are emotional. if the introvert tells that the world is round the listeners will only reply that it is flat. so why speak something that leads to nothing? if the introvert says ive done this, i experienced that, all the reply is, that's not true, thats impossible to happen, your just inventing things. again why bother to talk when no one believes? shutting up is the only way.

I feel inferior in many aspects but i think my opinion is valuable and i don't mind sharing it or speaking in public. Im not an introvert type, but i have almost no friends.
