Turning 21 soon and been kind've disillusioned with many years of my life so far. Feels like I wasted my teen years and feels like didn't enjoy highschool or university as much as I should have. I know 21 is young but where do I go from here? Of course purpose/career is of primary importance but are my best/most fun years behind me? What should my mindset be going into the future? Loaded questions but any advice would help. Thanks.
