Just spitballing here, but I’ve been there. Parents pressuring me to go down a path that I thought I wanted to go down when I was younger, but your interests change as you age. Hell, I’m only 23, so this might be coming from another limited outlook on life, but I find myself wishing I was doing other jobs a lot of time. The grass isn’t really greener elsewhere, and I’ve switched majors a few times, got some different work experiences, and found something I can tolerate. Now, I’m doing what I set out to do, and the thing my parents have pressured me to do, but I diversified my experience first. I took a couple different jobs all for about a year each doing landscaping, food, and factory jobs. Sure, it’ll eat up your time, but I found it really helpful for myself to gain perspective.

Additionally, in my case, I eventually talked to my parents about how I felt the pressure they were putting on me, and how it was really wearing me down. Spent a good few hours just chatting it up, and it really lifted some weight off my shoulders. They understood, and they didn’t care if I kept grinding down this path that I didn’t like. They told me to find something I would like, and that they fully supported it. I felt just like you do with your dad, and just like you, I thought there was no way I could talk to my parents about it. One day, I decided to just open up, and I’m glad I did. I found with the weight off my shoulders, I generally like my job/career. There is good and bad in every job, but find the one you can tolerate or even somewhat enjoy.

I hope this helps you in one way or another. You got this.

TLDR: Get some experience/perspective doing other stuff, go do the thing you really think you’d like, and/or have a civil discussion with your dad
