And this doesn't motivate you? For me it's actually more motivating: I only have to muster enough willpower to start walking, not to run, but I'll end up having a good workout anyway.
That’s only a motivation if you viscerally believe running to be an enjoyable activity. I have found that when starting something new, the most important (and hardest) thing is to stop while I’m still having a good time so that I associate that good feeling with the activity instead of the pain that comes from overdoing it.
