I think few do a job they love. In all jobs you have to work with people you don't get on with, do things you don't necessarily agree with and basically sell yourself out. But that doesn't mean you can't blog, travel or do anything else you love in your spare time. The people I have met that truly love their jobs tend to be married to their work and their personal life sucks so it is swings and roundabouts.
That said, not working because of lack of vaccines, not starting your own business because selling is difficult or not writing a blog because someone else does it sound more like excuses to me. If you want something you are going to have to work at it and that includes a fulfilling life.
I have been in work for 15 years. I have nailed my private life, but still have some way to go before perfection is achieved in my work life.
Good luck and don't give up before you have even tried.
