Currently I am in school for automotive technology (fancy words - just auto technician) but its a direction that my father didn't like. He thought it was a waste of my abilities and I entered the field to late with no experience and less knowledge.
This makes no sense at all. Too late? It's not figure skating.
My advice is if you are enjoying it keep going, get a part time job at a mechanics and end up employable. Meanwhile get some math tutoring or take a course at a community college or even just do an online or youtube course in calculus and figure out if this is going to be something you can master. In other words, dip into the math in a no commitment way and check it out while continuing your path.
If at some point you wanted to change careers at least you will actually have a career you can work part time in to fund your career change.
