21: The Tin of Trail Mix (home made)
When you are being excellent you'll be burning up those calories. Whether writing, teaching, playing lego or chopping wood: energy levels will sometimes need a boost before the next meal. That's where trail mix comes in. Mix your own with the purest of nuts and dried fruit: find a supplier who doesn't tarnish them with odd oils nor dubious 'candied' peels and the nuts are clearly fresh, the best quality and without salt. Although some (traditional) recipes add chocolate leave that for true hiking and/or space missions; work near your home base doesn't need sugar high and lows. Find an air-tight tin and keep the perfect excellence restorative across the room, never within an arm's reach. Just saying.
