I've always been very quiet and shy, and although I really enjoy conversation with the right people, I find it hard to talk to random people and engage them in conversation. I always feel like I have to have some reason or excuse to talk to someone new, and I usually just wait for someone to approach me. The funny thing is, I (for the most part) actually enjoy random people talking to me, I just don't randomly strike up conversations with people. I assume this is probably true of most INTPs, but recently I've been trying to break free from this mindset, it's just that I find it very hard. Is there any advice people can give me on being more assertive without fear of rejection?
