Anything that causes you to use time, energy or money less efficiently generally contributes to one being less effective, successful or productive. I've built this element into a few of my game designs, where, for example, the player can acquire assets or skills which reduce the future time/energy/money cost of doing something worthwhile or necessary. So it's like an investment where the payoff is an accelerating factor on everything else the player wants to do.
