Before you sweat the logistics of focus: ๏ฌrst, care. Care intensely.... Obsessing over the slipperiness of focus, bemoaning the volume of those devil "distractions," and constantly reassessing which shiny new "system" might make your life suddenly seem more sensible - these are all terrifically useful warning ๏ฌares that you may be suffering from a deeper, more fundamental problem.... Know in your heart that what you're making or doing matters... First, care. Then, as you'll happily and unavoidably discover, all that "focus" business has a peculiar way of taking care of itself.
Merlin MannEmail is such a funny thing. People hand you these single little messages that are no heavier than a river pebble. But it doesn't take long until you have acquired a pile of pebbles that's taller than you and heavier than you could ever hope to move, even if you wanted to do it over a few dozen trips. But for the person who took the time to hand you their pebble, it seems outrageous that you can't handle that one tiny thing.
