Answer:
Well i believe it depends on the person you are because then what ever specialty you enter you reward full and enjoyable e.g
If your a caring or find happiness in helping others then you can enter specialties around it and not be disappointed in tour choices
Also I would like to add if you do regret your choice then you can switch careers if you really think that work suits you more. I have a friend who used to be an head engineer for a car dealer ship but ended up switching careers at 37 years old. So don't think that you entering a certain specialty mean you can never switch careers.
I whole heartedly wish you the best in what job you enter.
