Thinking about fundamental objectives and means objectives is relatively easy when the decision context is narrow (buying a telescope, renting an apartment, choosing a restaurant for dinner). But, when you start thinking about your strategic objectives -- objectives in the context of what you choose to do with your life or your career -- the process becomes more difficult. Spend some time thinking about your fundamental strategic objectives. What do you want t accomplish in your life or your career? Why are these objectives important?
Try to create a fundamental objectives hierarchy and a means objective network for yourself. Obviously this will change over time and as your career and personal situation changes, but, it is an interesting exercise to undertake.
