Which means that every time I set out on a walk, I go in a new and different direction, one that most surely--I decide at the last minute--will lead to a level path.
But what really happens is that I spend about 90% of the first part of my walk going downhill, (because the downhill option ALWAYS looks better than the uphill option). But then eventually I decide I'm just going to have to go home, and since there's no level path in site I decide to just turn around and go back, which means of course that 90% of the homeward journey is going uphill.
This morning, grunting and groaning on that uphill part of the journey, I decided maybe, just maybe, there's a lesson to be learned.
I'm still thinking on it.
