Have you ever looked into a bachelor's degree in music education? Not sure if this angle interests you - inspiring and interacting with young minds whilst doing what you love. My daughter's secondary school music teacher actually took leave last year so as to travel around Australia with the band he was in (the best of both worlds). By the way, being one of the most easy going yet hard working inspirational teachers at the school, he is also one of the most adored teachers.
I think if Law is not your thing, don't waste too much time staying in this obvious ongoing state of mental conflict. Sounds like it's taking you further and further away from who you want to be, which reminds me... I once read a sage piece of advice - Don't ask 'What do I want to do?', instead ask 'Who do I want to be?' Perhaps this is advice that should be handed out by all secondary school career advisors. By asking a kid 'Do you want to be a creator?' they can take it even further by asking 'Do you prefer to create more-so through the mind or through the hands. The 1st list may involve interests such as Design engineer, Website creator and so on. The 2nd list may involve more trade based learning and work, such as Carpenter, Welder etc. Or 'Do you want to be a leader and, if so, in what area? Leading through teaching, leading through politics, leading through mental well-being (leading people to a greater state of health)?' Identifying who we are can help us then identify what we want to do in the way of career. Being a mum to 2 teenagers, I will often remind my kids of who they are so no matter what they choose to do in life (in the way of future career), they can chop and change paths whilst ultimately remaining true to their most authentic self. There is a natural joy in that.
So, the question... 'Do you know who you want to be?' I believe, sometimes, when we look all the way back to our earlier years, we can find a hint as to who we really are, through that imaginative young soul with perhaps grandiose dreams and goals. Be it the adventurer, the musician, the writer, the seeker of justice or the hero, perhaps one of the greatest conflicts of the mind involves the question 'Do I re-turn to that aspect of myself or do I continue to turn away?'
