Hi Tad! I am so glad you posted. I think of you and hope you are well. I am glad you have found things you are interested in. And, I totally think it's ok to be more of an introvert now. Things change, and we change.
I have always been an extrovert and thrived off of being around others. Now, I cherish my alone time. The things you are doing with your time sound so peaceful and fulfilling to me.
I think you have to really go through a transition, like wean yourself off from an old lifestyle to appreciate the a quieter, yet more fulfilling lifestyle like that.
Good for you, Tad. You sound good, and that makes me happy.
