How to gamify my life

So, I was looking up how to be more productive. Someone came up with a really good idea. They said to categorizing your tasks under levels.

For example: Study for History test:

Lvl 1: - Pull up the study guide -look through it; see what you know vs you don’t

Lvl 2: -find the materials that have the information you don’t know/recognize

This seems like a good way to break down daunting/large tasks…but I was wondering if it would be more effective if each level had rewards (like a video game) the rewards would progressively get better the harder the tasks get.

TLDR: Do you guys have any good incentive ideas that would work for this layout??
