haha, I don't practice these little tricks with strangers, or all the time.

Just with friends, and a few times I can consciouly remember it while talking.

I have read a few books about body language, watched a ton of videos, must have taken a few courses.

But you don't remember all the things you read, or watch.

It's just the little things you practice over and over that you get better at them.

You are right, finding the right balance is the key🙂
