People like to throw around the old saying ”do what you love and you never work a day in your life”, which I always thought of as bullshit. You bring out a good point regarding that, it only works out if people are willing to pay for what ever that other person is offering. I am pretty lucky to get to do what I love, and make a living out of it, at least for now.
Eventually, in my experience... doing what you love for work ends up in an eventual dissonance to that "love". It can become a chore, or feel monotonous. Perhaps that was me working too hard at it, or maybe I didn't "love it" to begin with?
I can agree on that too. I already killed one passion by making it my job, cooking. Maybe I was never in love it, or maybe the job ruined it.
"Do what you love and you may never earn a dollar in your life" but it might be valuable to you. Some people do the most terrible things in the world so they can have a glimpse and taste of what they love. Most people in this world have the possibility but instead avoid the doing.
