Solid post and there's a lot to agree with. However, one statement was difficult to digest.

If factors like "health", "happiness", or "family" rank below professional goals, your long-term priorities are not stable.

The second factor, happiness, is probably the most difficult of the three to qualify. Professional goals and happiness may be intimately related for many people, and activities that bring more immediate happiness may be ones that detract from long-term satisfaction. Maybe a more accurate way to put this would be to avoid pursuing professional goals if it involves sacrificing life goals.
