As the old adage goes, preparation is only half the battle. Planning tools like the Eisenhower Matrix (discussed in an earlier blog post) can certainly be used to resolve conflicting priorities when developing your plan, but a successful plan also entails regular evaluation.
In terms of our health, we often schedule appointments when we feel under the weather. Preventative care, however, (much like management development training), works at the opposite end of the wellness spectrum. It requires initiative. By the same logic, we can check the health of our own plans before things get awry.
