Agreed. Why usually comes first, followed swiftly by How and What. Like Spook, knowing the why helps to motivate me into action. Since I have already resolved the most important question of "Why am I here?" everything else is in relation to that purpose.Depends on what I'm asking... but why usually comes first, that's what motivates me to ask how and who since there usually isn't a sufficient/objective/all-encompassing answer for why.
