We always hope for the easy fix: the one simple change that will erase a problem in a stroke. But few things in life work this way. Instead, success requires making a hundred small steps go right - one after the other, no slipups, no goofs, everyone pitching in.

Life is choices, and they are relentless. No sooner have you made one choice than another is upon you.

We've created a multitrillion-dollar edifice for dispensing the medical equivalent of lottery tickets - and have only the rudiments of a system to prepare patients for the near certainty that those tickets will not win. Hope is not a plan, but hope is our plan.

One of the consequences of if the Affordable Care Act is repealed, is that all of us now are at risk of being a preexisting - of having a preexisting condition waiting to happen. Life, increasingly, is a preexisting condition waiting to happen, now that we have more and more of this data available.

The big thing that's happened is, in the time since the Affordable Care Act has been going on, our medical science has been advancing. We have now genomic data. We have the power of big data about what your living patterns are, what's happening in your body. Even your smartphone can collect data about your walking or your pulse or other things that could be incredibly meaningful in being able to predict whether you have disease coming in the future and help avert those problems.

What is needed, however, isn't just that people working together be nice to each other. It is discipline. Discipline is hard--harder than trustworthiness and skill and perhaps even than selflessness. We are by nature flawed and inconstant creatures. We can't even keep from snacking between meals. We are not built for discipline. We are built for novelty and excitement, not for careful attention to detail. Discipline is something we have to work at.

Coaching done well may be the most effective intervention designed for human performance.
