answer:I think in your case you can. You are still young and you’ve got a long life ahead. It isn’t too late for you to change now, as long as you have thought carefully about what to change. But you have to think carefully. Will you benefit from the change? Or will you just waste time on another meaningless work? You have to consider before changing or you will end up feeling horrible like you are now (and worse, you realize that it’s too late to make anymore change). Life isn’t that long for you to change without thinking. Your guardian suggested that study because they thought it suited your ability. It isn’t enough. You need to like the study to learn properly too. If you like the study but you don’t have the ability needed, then you can’t study. You said that you like neuro-psychology and the like, so you already know what you want. You can change to that, but you have to consider whether you have enough ability to learn it. And you don’t really need a lot of money to work. You have a well-paid job but you don’t like it, you still can’t work. Listen to your heart, study what you really like, and success will come to you.
