Well when I first joined, I was really young, probably around 12. Its been four years since then, and I do have to say I think I've changed quite a bit from that time. Perhaps back then I was a little more annoying, always asking to join groups, being /too/ outgoing, etc.
I still would always love to use the forums as a way to communicate and help others. That at least, hasn't changed much for me. I have to say that I was and still am quite the mature person for my age. xD But I often get mistaken for someone 2-6 years older than my current age. So I guess you could say I matured a bit as well. Back then I was a lot more shy, less willing to joke around, very worrisome about the internet, etc. Now I'm super outgoing, friendly, talkative, and helpful.
Its very interesting to look back on yourself and say, "Wow, that was me?" And I think with age comes a better sense of self-improvement. Normally, younger people aren't typically out to create a good image of themselves, impression, etc. They're generally just trying to have fun and be accepted. But as one gets older, self-improvement becomes a very important topic. It's probably quite psychological at this point, having to do with the human brain, outside influences, etc., but I think part of aging and maturing is realizing that your outward appearance (not just looks, personality too) matters when it comes to others, and that making a good impression and whatnot becomes a valuable asset to creating relationships. This ultimately leads to the desire to want to create a better/more mature version of yourself. It's quite strange actually, and I guess it could be described as somewhat disheartening that socially and politically we are pushed to always be a greater version of ourselves, but honestly and personally, I believe that you're born with set qualities and personalities and that no matter how you age or change, they'll always be there with you. Perhaps some qualities just hide inside of you until a later period of your life. Whatever the reason is though, I think the most important thing is to remember that who you are is who you are, and you shouldn't have to feel like you have to act a certain way to be a great and admirable person. c:
