One of the things it’s hard to fathom as a teen is that most professions with good pay and conditions require that you identify with the job and get real satisfaction out of doing it and being it. Those satisfactions vary obviously depending on the job and person. I’m speaking as someone that made a midlife shift to being a university professor. Very decent income but you had to really commit to the field and trust the process to get there. Not IB money or winter circuit money but good enough for me. Same is true of you’re in law, medicine, politics etc etc. You can have big expensive hobbies like a horse for sure once you are established but you won’t get established if all your identity and sense of self is wrapped up in your horse.
A professional identity is something you grow into over time in your 20s. It’s not something you have at 15. It’s normal and good to have a huge emotional commitment to a hobby or sport or horse as a teen. But as you go through college and your 20s hopefully you find a profession that you can whole heartedly buy into and that gives you joy and identity and autonomy.
As a teen I only felt those things around horses but as an adult I have multiple sources.
