I wonder how many hours that would have otherwise been productive have been spent reading about productivity.
Reading about productivity can be useful, IF you use what you read. Most don't.
I think many many are in a similar boat. I try to tell myself the above and realize that I should spend my "reading" time on things other than "productivity." I.e. planned procrastination isn't a bad thing. Just don't fool yourself that you're being productive.
Kudos to you for having projects that keep you motivated though.
