Somewhere between my comfort zone and what I think is totally insane is where I try to climb. Too comfy and I get complacent, too scary and I just get pissed off. A small dose of adrenaline, just a taste, and I'm good.
We all talk about how you can do everything right and still get whacked, but I think the reverse is way more common, we can get away with plenty of stupid shit almost every time. Oh we learn and get better at avoiding those situations but there are lots of chances to fuck up in the hills. Maybe its just me but I doubt it.
