Over organization can kill the spirit. Especially in creative endeavors. Let's say you are working in independent game development. And you alone are responsible for all design, tech, art, music and distribution. Allocating hourly intervals for each task at a set time each day can breed monotony. Rather, when you feel that inner fire to work on the music. Focus solely on that one task for an uninterrupted period of 4 hours. And always with the tools of reinforcement to show steady progress, such as documenting everything and visualizing milestones.
I thought it was really interesting to hear about Ninja, the fabled Fortnite streamer, talk about his work ethic. Which was basically to have two 4 hour chunks of livestreaming per day. One in the morning, and one at night. Separated by a 4 hour slot in the middle to spend with family and friends. He's had the discipline to keep it up for a decade, even when few people were watching. But having that accountability of an audience to livestream to, provides the impetus for daily progress.
Best of luck ;)
