You should ask yourself why you dislike that part of your personality.

For me, I had accept that it's part of my DNA.
It's not a matter of giving up so much. It's just that you can dye your hair if you don't like it, but this is much harder, or impossible, to change.
I've never liked boisterous, loud people anyway.
Don't want to be one.

Whenever I find a characteristic
About myself that troubles me. I imagine what I would be like without it. The end result. Then depending on how much I want to change that characteristic, spend the time and energy to get to that end result. To not be an introvert,...you must develope an interest in others. Pretending to care about others is a start. Good luck with your life.

Why would you want to? It’s not a bad thing.

Get out of your comfort zone and be a little spontaneous sometimes. But at the same time don't let others force you into not being yourself.

As far as I'm concerned, my introversion is not a problem or a disability, it is what it is.... and I'm cool with it.

If you have a dog, take it for walks in the local parks. They're great ice breakers with people.... if you don't have a dog, why not?

Force yourself a little at a time until you can do things

You'll never not be an introvert, just recognize what being an introvert is and what it is not, and how it can hold you back. An introvert is not being generally shy or "lazy to start conversation". Think of being an introvert like having a "social battery" - when it's charged, you can talk to people and generally have a good time in a crowd. When it's drained, you just have to go do your own thing for a while and recharge. That is totally different from being shy and not talkative. My advice? Fake it til you make it! Worked for me. Learn how to converse the right way as well. Open ended questions such as "What do you like about what you do?" as much better than "Do you like your job?".

I used to have same problem. I was shy and introverted. Now people find me the life and soul of the party. How did I do this? Well 1st I realized that I had a problem that had to be dealt with. I was definitely not happy with the status quo. Then I thought about the most extroverted guy that I knew. This chap was outrageous and would often piss people off but he did not care. So when I felt shy or backward I would say to myself "what would x do here?" Then I would tone it down by half (I didn't want to cause trouble) and act like him. After a while it became natural and part of who I am.

Drop some acid, that should probably do it. ?

A compliment is a surefire conversation starter - where'd you get that shirt, it looks great on you. That sort of thing. As for carrying your end of the discussion, you're on your own there.

Put yourself in a position that requires you to engage, immerse yourself in groups that require conversation. Look up conversation starters on line. Feel the uncomfortable feelings and do it anyway, eventually you may become at ease with it. Just offering a suggestion, good luck.

Let me know when you figure it out.

I think you'd find your conversation will flow freely if people of comparable intelligence are discussing something with you that you are passionate about.
Also be aware that beautiful women can make many males tongue-tied.

Before I learned to take derris scandens-which eliminates gender dysphoria and blends my gender sides- I was gender; fluid-switching back forth between male and female perspectives.

When I was in male mode, a pretty woman could make my feet feel so huge I could barely walk, and make my tongue seem to swell and freeze so I could barely say anything.
My only hope was to force myself back into female mode, or pretend the girl was male.

A character trait is very difficult to overcome since it defines you. I would suggest that you seek out groups, events or gatherings on subjects you are good in or that peak you interest the most. We are always comfortable talking openly about something we are proficient in doing.

If all else fails, stop watching porn (@The_Antichrist)

Its so hard, I stood in front of 600 students and I nearly wet myself! I had a serious derealisation experience and I am mental health nurse! Then I remembered Shakespeare. He said stick your courage to the sticking place. (Or words to that affect). As in you are going to have all those nasty anxious feelings, just do it anyway. Or in the words that have carried me through every single major decision in my life...one...two...three..f**k it!

Stop watching porn.
