A crucial aspect of purpose is that it’s always worked towards, but never fully achieved, like chasing the earth’s horizon or pursuing a guiding star. The enduring aspect of purpose is well illustrated by Steve Jobs, co-founder of Apple and founder of NeXT:

I don’t feel that I’ll ever be done. There are lots of hurdles out there, and there’s always a hurdle that I’ll never reach in my lifetime. The point is to keep working toward it.

Unlike purpose, which is never achieved, a mission should be achievable. It translates values and purpose into an energizing, highly focused goal—like the moon mission. It is crisp, clear, bold, exhilarating. It reaches out and grabs people in the gut. It requires little or no explanation; people “get it” right away. Once a mission is fulfilled, you return to purpose to set a new mission.

5. Objectives, goals and actions: how means help us discover the end

An old story tells of a visitor who encounters three stonemasons working on a medieval cathedral, and ask each what he is doing. ‘I am cutting this stone to shape,’ says the first, describing his basic actions. ‘I am building a great cathedral,’ says the second, describing his immediate goal. ‘And I am working for the glory of God,’ says the third, describing his high-level objective. The construction of architectural masterpieces required that high objectives be pursued through lesser, but nonetheless fulfilling, goals and actions.

Objectives, goals, states and actions evolve together because learning about the nature of high-level goals is a never-ending process. The distinction between means and ends, which seems obvious and important in simple problem solving, is, as Lindblom explains, not central to practical decision making. The process in which well defined and prioritised objectives are broken down into specific states and actions whose progress can be monitored and measured is not the reality of how people find fulfilment in their lives, create great art, establish great societies or build good businesses.

My mission is to live with integrity and to make a difference in the lives of others.

To fulfill this mission:

I have charity: I seek out and love the one—each one—regardless of his situation.

I sacrifice: I devote my time, talents, and resources to my mission.

I inspire: I teach by example that we are all children of a loving Heavenly Father and that every Goliath can be overcome.

I am impactful: What I do makes a difference in the lives of others.
