I'll share some of my perspective, but each person is different, my passion is not your passion.
I think more about things like meaning and motivation than passion. Passion is something that often declines over time, at least temporarily, even passion for a wife in a long marriage or someone like that. It's important to have more.
The word passion has roots in suffering, meaning a willingness to face the hardships. It's not something to search for enjoyment. My hobbies are more related to enjoyment, my career not so much. Of course, I try to do something I enjoy, but it's not a requirement.
If you compare yourself with others, than marketing probably isn't for you. It will be hard to find a career that is a good match. Great marketers often are differentiated, setting trends, following their own paths, lone wolves. Job titles are often meaningless. It's not about others, it's not about my titles, it's much more about doing something that makes sense to me. There is nobody in the world like me. Comparisons don't make sense in this case.
Manipulating others often doesn't make sense to me, because often it's the company trying to manipulate me to do what they want. Not to do what I want. But I know manipulation is subjective. I may be trying to manipulate you by writing this. That doesn't mean I'm evil or I want to do something bad. I may manipulate people to inspire them, for example.
Competition with other ideas is often exhausting. But I do that because I believe in those ideas. Giving up on them may be less exhausting, but is wrong and would make my life meaningless.
A very important part of the journey is finding jobs, companies and people that are right for me. I won't be passionate for someone or something wrong for me. I had bad jobs, bad bosses. I hated them, it doesn't make sense to have any passion in those cases. Finding your passion probably requires finding the right jobs, companies and people. Not only marketing in general, you should be much more specific.
I left the industry after a long career to become a professor. So, studying consumer behavior became more important. Still, studying is far from enough to me. If I wanted to focus on studying, Psychology might be better and more theoretical. Marketing is a lot about action to me, not only studying.
An analogy to me is comparing marketing and marathons. The theory of a marathon is easy. Running a marathon is much harder. Becoming a champion running a marathon is much harder. It's not something we do for enjoyment or just out of passion. If one wants to study and do things for enjoyment and passion, trying to become a champion running marathons is not a good match.
