If you’re a spaceship in an intergalactic movie, you can go faster, you can increase your defense shield, or you can increase your blasters…but not all three…the ship can never handle all three.
If you’re custom NBA Jam character you get to choose where to spend your avatar bars…do you want to use them all on height and dunking, or spread some around to shooting and speed and defense too?
If you fuel up in Nashville you can drive to Atlanta or Cincinnati, but not both.
A simple metaphor worth remembering.
Where will we spend our (limited) energy?
