Less is More. Do less and then do what you do brilliantly. You only have so much attention, so much power, so much energy, so much focus. Use it wisely. Yes you can do anything, but you can't do everything. Get rid of physical stuff; have only that which is useful and/or beautiful. Strip back technology to the essentials. Decide the crucial communication channels and ignore the rest. Address your vital few and automate the trivial many. Less is dramatically more.
