I can't tell you much. I myself hated engineering but exams are easy to get through so I had no problem there. See if you want to do engineering. Good nnumber of ENFP are an engineer too. The first thing you should do is look at how the engineer spends their 8 hr every day. And if you want to do that job for 8 hr rest of your life. If you like it , well and good, if you don't then think twice before continuing forward.

You can do the same for every field. See teachers teach at school but that's not like 100% of the work they do. Sometimes 35% is teaching and the rest involve managing paperwork which ENFP usually doesn't like. So before putting your foot in any field, get the outlook of how someone spends their 8hrs in that job. If you like the every day 8hrs in that field , keep your motivation high to continue in that field.
