A goal-setting system that works only 70% of the time is broken. The speaker compares it to a light switch or car that fails that often, then argues the real problem is you. Define a minimum acceptable level and hit it every time, not most times.

I want you to think about this when you're talking about your system and its efficiency. Your system is 2,500 calories a day. That's the goal. If you're only doing that 70% of the time and you're satisfied with that, think about this. If you were to turn on a light switch and the lights only came on 70% of the time, or you booted up your computer and it came on only 66% of the time, or started your car and it only turned over 75% of the time, would that be good enough for you? Of course not. Yet what this illustrates is that the weakest component of our Goal Setting and Achievement System is the human at the controls, and we have to learn to not settle. Enough, it means enough, enough to sustain, to be able to maintain and sustain that activity in our lives, but also to get some sort of minimum acceptable result. So that's what we're doing at the sufficiency stage. Where are we starting at, and what does a minimum level of progress look like?
