I like Cal Newport.
He wants us to get more good meaningful work done and spend less time on email or social media. That seems like a worthwhile goal to me.
One of the key productivity methods he uses is Time Blocking.
I have used and still use a similar method myself, but having seen the video below, I think I might modify my system further.
Watch the video and see if you like the method, and if so consider purchasing his time-block planner or mocking up a similar one in a notepad.
