If you're not familiar with the Pareto Principle than you may have heard it referred to as the 80 / 20 principle.
The Pareto Principle states that roughly 80% of the effects come from 20% of the causes. This is a pattern that can be seen in many places such as income, sales, wealth, etc.
I've continually found this principle to take effect in my game development projects. Once I'm about 80% complete the effort to push forward seems to be just that much more.
Continually inspiring myself to create this project seems to be half the battle.
If you're feeling out of juice, what helps you to become re inspired and motivated?
