Am i making a bad decision?? Ok so i have been studying mechatroincs for around a year and a half and now after i know more about the subject it isnt as interesting as before. My problem is that i want to study and hopefully work in an area that iam passionate about and its kind of a big deal for me i do have a mild form of depression sadly and working in a job u hate for the rest of my life would be quite bad i think,iam not interested as much in a high paying salary as much as working in a job that is fulfilling a job i wouldnt hate waking up at morning to go to. which after much spiritual search turns out to be these four art(painting or music),philosophy,mathematics,and physics. I actualy wanted to study philosophy before going into mechatronics but later after reading through forums and other ppls experiences i got scared from it every one says u wont find a job as a philosopher,so i though getting a bs in mechatronics would be a plan B for me if things didnt go well trying to find a job i like. But things didnt go well in mechatronics the university my parents chose sucks i study from the book most of the time cause i dont understand anything in the lecture,and i believe iam wasting time. So i decided that iam going to change my major to physics and go on to study and get a phd. Is this a bad decision??? Is doing research in physics intellectually stimulating or am i going to get disappointed iam asking this cause i dont think undergraduates know what a job is like till its too late.
