It is worth remembering that the skills and the interests need to be combined in your life, not every day at work. Maybe you are passionate about gardening so you have a good job that pays well and keeps summer hours, letting you spend your weekends gardening.

I have a passion that I engage with for a living (math) and it's currently keeping me underpaid. I'm also very interested in art and so I go to museums, work on learning how to paint, etc -- and if it was my job, I'd stop liking it. I like it so much because it's a complement.

Some passions are like hot sauce -- a sprinkling makes almost every food better, while a full bowl gives you the runs.
