Whenever I read one of these posts I'm always very curious about the age of the writer. I find my thoughts on this topic has changed a lot from mid twenties to mid thirties.
But the reasons for procrastinating, those are spot on.
It's the complete absence of influence of other people (be it in the form of SOs, kids, coworkers, office environments, meetings, bosses, customers, what have you) that makes it alien to me.
If I could have 4 hours of real, concentrated, productive work on important things each working day, I would massively increase the impact of my work.
