Living cannot be done through desk research. You can only truly experience life through experiencing life. So give yourself as many real experiences as humanly possible. Especially when in doubt, scared, or unsure, leap into something new. Not because of an end goal, but simply because of what can be found in the new experience itself: a new experience.
The younger you are, the more risks you either can afford to take or will dare to take. I would advise you to do so. The more you explore now, the more you will actually know better by the time you are old enough to know better.
As long as it will not endanger or otherwise harm you or others: if it leads to joy, makes you proud, helps you grow, helps you open yourself up to someone, helps someone else, if it could become a beautiful memory, if you keep wondering ‘what if…’ or simply if it’s a thing you would really love to do but you have no rational reason for, no permission, no guarantees or no courage: do it anyway.
Even — or especially — when it’s something you may fail gloriously at: do it. Failing will teach you so much more than succeeding the first time.
One of the top regrets of the dying is all the things they wanted to do, but didn’t. It might be better, then, to get it wrong and either apologize or do better next time, than to never have tried at all.
