I've matured a lot since I was a kid and definitely my personality has changed. One thing that hasn't changed however is that I'm not really good at talking to random people or even people I just don't know and or making friends. I feel like other INFP's are better or more sociable than me, I'm pretty introverted, I can really spend most of my time alone with my thoughts, so I don't really *need* lots of social interaction so to say. But sometimes I would just like someone to talk to, for example in a class I take, and there isn't anyone. It occurred to me that I've made only one friend over my whole time (now 3 years) at university. Sometimes I will get along with the people I have tutorials with but not in a way that's like, when you come back the next week you know you can talk to that one person about things.
Anyway. Maybe this is just a part of my personality that will never change, since other parts have and I've gotten much better or even more confident at a number of things but this hasn't changed, I am thinking that maybe it is. I know there are some generic advices that can be given like, oh you just need to talk to more people and be more sociable. That doesn't really work, since for me, either you click with someone or you don't. For the people who have been my friend or at least like what I'm saying I instantly feel a vibe from that person that I can talk to them easily, and I assume vice versa, and that they will understand what I'm saying or just be able to communicate easily. So if I want to talk to someone but they don't initially have this vibe then I don't feel like I'll ever have more success anyway.
So I made a little anonymous poll anyway for you to say how you feel you do at this. When I was a kid I didn't but nowadays I spend a lot of time on the internet. I feel like the responses here versus INFP's in real life will be a little bit more geared towards loneliness or maybe I'm just judging the internet too harshly.
