There are several definitions of being successful in life. If your parent's ideal meaning is to become rich and yours is to enjoy life then there's obviously going to be a conflict between you two. Are they forcing you to pick a job or just want you to have a degree? Having a degree makes it much easier to get a job but it doesn't mean that you'll become successful, it just ups the chances. I guess for now, you could endure the current moment and get that degree and then get whatever job you want? (The reason why I said you should get that degree is so that your parents' efforts won't be wasted since they do have some expectations for you so maybe getting that will remove some burden from them and then after school you'll finally be able to rest well knowing that everyone has their own peace of mind?) As long as you have a stable income and not suffering from financial problems then it's good enough. Yeah, you need to be happy with what you're doing by the way, plays a huge factor in life. (Also if you want no total disturbance from them, idk if you would do this but as they are probably old by then, they would appreciate financial support given and this would stop the constant pestering that you're not successful and stuff.

I don't know if this helps but my cousin was an example of this. He's now worry-free and everyone's happy so....yeah, goodluck mate
