In Out There today we have a story exploring the feeling of "flow." That sense of timelessness and total integration you get when you are fully engaged in an enjoyable and challenging task. I talked about it in terms of skiing, biking and running, but just as many people enter flow playing music or even writing software code.
Personally, I slip into the state occasionally while writing, more often when drawing the periodic comics I do for the Gazette, and most often when I'm mountain biking.
On certain trails on certain days, flying downhill, I don't notice the bike. I don't notice thinking about steering or avoiding obstacles or balance. I feel invincible, like I can do no wrong.
I don't get the same feeling running. Here and there, when I'm well trained and doing well, I'll get what I might call a "runner's high" where I can sort of step outside myself, see how well I'm doing, and enjoy it, but it's not the same seamless feeling of being one with the bike.
Anyone else? What makes you enter flow?
