ok guys tell me.which one do you prefer when you are choosing or deciding in which course should you master in?

Like,do you prefer the one that you love,that you are passionate in it but doesn't make much money

OR

The one that generates money in future,a wide oppurtunity of getting employed.

I have a friend of mine,she shared her thought with me...she said,if we choose something that brings us money,we'll have a career,but if we choose something we love,we'll enjoy our life.

So guys...

WHAT SAY YOU?

Feel free to share your thoughts down there ;D
