I can totally relate. I often find, more often than not, that I am more of a silent observer; and unless the topic turns to something I'm really passionate about, I feels like it's not worth the nervous effort to jump in, especially in a group. Not that it isn't, it's just hard to stretch my comfort zone.
Definitely takes practice, little by little. I think sometimes, the reason why I don't invest more in the effort is because I still fear rejection so much, even if it's a minor slight. Even though it's ridiculous, it can feel like an attack on my identity.
