I see a third option: you can decouple passion from attachment. Equanimity is the opposite of attachment. This is pretty much the thesis of the Bhagavad Gita, this decoupling. With this third option, you can be extremely passionate, give something your all, and at the same time be equanimous: deeply ok with things as they turn out. In our experience this third option actually helps our ability to succeed in our goal, because all the effort spent stressing and worrying and getting yourself riled up is energy that would be better spent just passionately trying to achieve the goal.
“We are in an age that assumes that the narrowing trends of specialization to be logical, natural, and desirable… In the meantime, humanity has been deprived of comprehensive understanding. Specialization has bred feelings of isolation, futility, and confusion in individuals. It has also resulted in the individual’s leaving responsibility for thinking and social action to others. Specialization breeds biases that ultimately aggregate as international and ideological discord, which in turn leads to war.”
