I mean, "do what you love" is a fine plan A. It will work out for some people, either in the "their passion makes them the best makes them rich" sense or at least the "because they love their work, they are happy even though they are not rich" sense.
But it doesn't hurt to have a "find something to do for money that you don't hate and maybe even enjoy some parts of, and then find some other stuff to do on the side that makes you feel like your life has meaning" plan B in your back pocket.
