It depends on what you want, I think. If you are feeling lonely and would like to try to find more friends, then trying to meet with and converse with more people is essential for that. If you are happy the way you are, and don't feel that you are missing anything in your life, then don't change. There is nothing wrong with being introverted, except for the fact that others don't understand it.

Keep on, keeping on.

One morning I woke up and realized I had little to nothing in common with my oldest friends. The people I associate with most these days are those with whom I share a common interest. In my case it's dancing, so my "dance buddies" are the perfect friends. The chatter is minimal because we're on the dance floor most of the time. If you keep moving, you don't have to hear about anyone's grandchildren, home improvement projects or the minutiae of their day. Works for me.

I am I

I engage others on social media and find it rewarding, but these people are far away and can't assist me as a support system in my every day life. For the past two years I have stepped outside my comfort zone to engage others. I'm less lonely and have people who I can count on. Being single, this is so important to me.

There's no need to change at all, especially as you sound happy with your life. As Jean Paul Sarte said:'Hell is other people', and I think he got it right.

You can't change, but you can adapt. Pick and choose who you want to talk to. Challenge yourself to move beyond your comfort zone, but be aware of how much you can manage and don't force it. And don't feel you have to compete with anyone or you're some how "less than" because you don't socialize as much as someone else.

Dont Change

I'm proud of my introvertness(a word??). But I also love good conversation when it can be found. Not a social butterfly but I do like people, generally, but not all the time by far. My quick 2cts, don't change, even if you could. Still waters run deep and introverts are cool.

Don’t ever change to become part of the “norm.”
As an introvert, I am very selective in who I converse with. At times I may become involved in a fascinating conversation with a stranger, but I feel safe knowing I’ll never see them again. My few dearest friends know that we may have the most beautiful conversations, but are also aware that they may not here from me for long periods of time.
Accept who you are. Any true friend will cherish that. Life is to short to force yourself to be someone you’re not just to fit into society. Just be you

I feel the same as you, but what I am trying is to be able at least to be able to be social when it is needed. In many ways we need people around us, and they will decide based on sociability if they will or not be available.
So, yes for my POV the effort is valid, we are a social species, our power is in the capacity to socialize. Modern society has dealt with this (automatizing the organization) but there are many situations (most of them that we cannot foresee) that we will need people around.
If you live close to family or friends you can have a safety net already in place, but if you start moving far away or loosing contact you can become dangerously alone.

I used to believe that there was something wrong with me before I knew what introverts were. Now, I understand fully that I'm just different and if people can't accept me the way I am, then I don't need them in my life. I don't plan on changing who I am to please other people.
