I switched to only surfing the web on the last Sunday of the month. You can queue up all the things you want to read and read them then.
Also, I think you would greatly enjoy and benefit fromm reading The Goal. It unifies a lot of the concepts you have discussed, including working harder, focusing on output, etc, with some brilliant wisdom on finding and eliminating, one at a time, the bottlenecks that hold you back from obtaining more goal units.
