I’d like to echo Raphael’s welcome and his suggestions that you look around for current opportunities to do some research, extend yourself or explore your interests. It may seem like cheap advice, but from personal experiences, dwelling on missed opportunities (particularly when the choice wasn’t presented to you) and passively going through the motions of today, whilst waiting for future opportunities, are both likely to compound feelings of wasted opportunity.
You are at an age when so many possibilities are still open, in possession of intellectual gifts that warranted consideration of a four grade skip, so now and the next few years are likely to be the best time to seek or create opportunities to engage in activities you enjoy, or that will help you grow, realise your goals, or perhaps benefit others.
