First thing you need to learn?
Your dad makes you read? Can't relate because they couldn't stop me from reading. Everything and anything.
As for a lawyer there are other types of law besides criminal. Estate law, corporate law, etc. Not every lawyer is a liar.
You've still got plenty of time to decide. I just knew in 7th grade the very first time I set type and stepped into a darkroom what I was going to do. Nothing nor no one could stop me. And I am still doing it.
Be what YOU want. You're the only one who will have to live with that decision.
Your dad's not horrible.He only wants the best for a son he loves. If he was horrible he wouldn't care.
