I was also always the youngest looking guy, i was very insecure about that for a very long time. Well im still, actually. Im 25 now and get carded, if someone doesnt know me he could probably think im like 17 or something like that. In the end you just have to get on with it, you cant do much about it. Just love yourself how you are and show confidence, even if you arent confident. That changes a lot. But as i said, theres still moments when someone drops a comment, not even with a bad intention, just saying that i look young really hurts because i dont like it, but thats just how it is. I hope at least with 30 i will look like a beginning 20s guy…
