When did your last goal fall apart?

Hey, I'm Somesh. I make apps on my own, and I'm launching Plan90 here on the 17th.

It's an iPhone app where you pick a few goals and it writes a 90 day plan for you, then rewrites the plan every week from what you really did.

Why I made it: in my experience the plan I write on day one stops fitting by week three. I miss a couple of days, the whole thing feels broken, and I quietly stop opening the app.

So I'm curious how it goes for other people. Think about the last goal you gave up on. When did it start slipping, and why? Was the plan the problem, or was it just life getting in the way?

I'm still working out whether I've understood this right, so if you think I'm wrong, say so. I'll answer everything.
