I actually think it's absolutely fine to not be a natural and still want it, and that the comparison to a physical talent isn't perfect, because in something as complex as engineering management you can really get very good even if you don't have the natural aptitude, whereas if you are too short to play on the NBA, you won't play on the NBA no matter how hard you practice. You're right though that it's worth thinking if it's really what you want, or it just looks good on others. And then sometimes the only way to find out is by giving it a try.
