Well, you have to actually like the career and be good at it too. That's why I said you haven't given anywhere close to enough information for us to give you intelligent advice. You simply said that you would work best with the hot boys. I see nothing wrong with that. It's natural for teachers, for example, to take a liking to some of their pupils over the others. Usually it's because they are the attentive ones or the ones that seem to have the most potential or the ones that remind them of themselves or of their own children, etc. In your case it's the ones you find most attractive. So, if you were asking about being a teacher, then the information you gave makes you no different from any other teacher and thus is not a factor in whether you should choose a career in teaching.

Now you are adding a different element. Now you are saying you actually would be terrible with those you aren't attracted to. If that's true; if you don't actually enjoy the career except for when you are with hot boys and you think you would do poorly with boys who aren't hot, then it may not be a good career move for you afterall.
