They say to never do what you love for work or it'll become a chore. Make time to be creative, even if it's only one weekend a month, it'll refill the creative juices and balance out the balance
They also say to do what you love, and you’ll never work a day in your life. They say lots of things, many of them contradictory.
I think your advice of intentionally setting aside time is wise, though. I believe that too often we take for granted that things will just happen, and also overestimate the chilling effect of “not being spontaneous”.
Do you need it to pay as much? I hope that someday you get to have as much creativity in your life as you want, friend. And that it's not only at the end of the world.
