Michael Wade, writing on his site, asks a few questions regarding time.

Is time linear or circular, an hour-glass, or ocean waves? Can time be managed or should it be regarded as an investment? Once lost, can it ever be recovered? If it could, would we know where it went?

Is time a collection of actions and omissions, moves and dodges, diligence and neglect, where the assessment of winning and losing largely depends on where the deadline is drawn? [One coach noted that his team really didn’t lose the game, they just ran out of time.]

The only thing that is clear about time is the usual request is for more.
