I get where you're coming from with people figuring themselves out throughout school. My daughter's 18 (this Wednesday) and my son's 15. While my daughter has taken years to finally find the most natural amazing friends anyone could ever find, my son still faces the challenges of sifting through to find those natural, sensitive, thoughtful, inspiring, non degrading 'friends'. My son is truly stunning in the way he's searched for friends. From prep onward, he would never settle for anyone less than a true friend. Having opportunities to easily make friends with many people, he'd often choose to sit on his own than sacrifice his nature, to fit in. Of course, there were times when this deeply challenged him, yet he's never changed over the years. He's never acted like anyone other than himself, which brings me to something you raised in your last post, your love of acting.
Personally, I've never been brave enough to put myself out there in the way of acting or public speaking. This is something I leave up to the stars, those who shine in such a unique and courageous way. When it comes to acting, I never realised until not too long ago how much we can act so unlike our natural self, in life. Our lives can be jam packed with directors, giving us directions on how to act. We can begin life as natural wonder filled little people, always asking 'Why?' to things until we're directed to 'Stop asking so many questions and just do as you're told!' So, we begin acting like people who don't question. We can begin life as 'challenging', often challenging those around us to rise to higher consciousness, to be reasonable, caring and sensitive in a number of ways (especially with their words) until we're directed to 'toughen up' and accept the unreasonable, careless and insensitive nature of others. To remain sensitive, a seeker of reason and careful is truly powerful.
I imagine philosophy interests you because you're naturally wonderful in search of meaning, you're reasonable in search of reason and sensitive to seeking what makes sense. The psychology aspect, I imagine you are someone who longs to make a positive difference to people, a guiding light in people's transformation. Perhaps that wonderful part of you also wishes to make sense of what and/or who leads (directs) people to act the way they do.
I believe, you're already a philosopher and, in seeking the light in yourself, you are well on your way to becoming a light for others.
