Pursuing one may slow you down
In many cases, making a career out of what you love only slows down your ability to do what you love. You just want to be a healer/chef/singer but when you make a career out of it you’ll spend a lot of time working on websites and marketing campaigns and social media outreach. Sometimes doing what you love not as a means to make money just lets you do more of it. You get to do it on your terms. No administrative tasks holding you back.
