Should I stay or should I go?


I’m confused sometimes when you say that you can be happy at any job (or marriage, etc.). I understand that you should find a way to be happy before you leave, but I still believe that some jobs are easier to do for one’s natural abilities than others. For example, let’s say you got on a path when you were younger and became an accountant, but you are terrible with numbers and details. Should you continue to stay there and try to make it work and give it 100% before leaving? Should you decide that you are going to make it work and not look back? Or say you are naturally introverted and shy, but chose a sales position because you thought at the time it was the “right” thing to do. It seems to me that this would constantly feel like you are swimming “upstream” and forcing yourself to be good at something that is not playing to your strengths. I see how you could “blow your own mind” by eventually overcoming something that was challenging but I also see how you could argue that it’s better to quit while you’re ahead and find something that is more suited to your natural strengths. Can’t someone be on the “wrong” path and switch as soon as possible, or is that a limiting thought?
I feel like the same argument could be made with regard to relationships and marriage. I suppose you could think loving thoughts about the person you are with, but I also see how maybe you’re not meant to be with that person anyway…
