Procrastination is caused by work being meaningless or insufficient incentives, not because people need to remember to do it or block out time.
Yeah, this. Having it on my calendar would likely have made it worse since than it turns into noise for the actual important things on my calendar.
If I used a tool like this I would have ended up missing so many important things like doctors appointments because I would have just ignored my calendar completely.
Also the idea of asking a system to find time to schedule this thing that gives me some joy in life sounds dystopian and screams messing up your mental health.
