Finance, accounting, actuary. I think what you need to do is sit down and see what you like doing and enjoying and what you don't and then narrow down a list of fields related to those traits and then do some research into those to see what is required to get there.
Do yo like logic, math, numbers, technical stuff?
then look into finance, accounting, programming, etc.
then see if it's halal/haram, then see what you need to get there , then find someone to shadow for a day to see if you would even like it
do you like helping people and being around people? then think about medicine, social service, theology, teaching, etc.
and so forth.
