Gamification

Test whatever (real) video game type!
Level up with experience, gain loot and use stuff! Gather resources and build something from them! Do a Tetris! Make a racing map and gain on others as you progress through your to-do -list! Run a little farther away from that closet monster when you complete a task! Grow from the tiniest particle to the biggest thing via going forward in real life! Gain money to buy a trade product, travel and sell it for a better price somewhere else!

Test whatever mechanics you enjoy in yer games!
Throw the die to see what happens! Just finished a bigger task? Roll twice or get a better chance for a better thing happening in your gamification system! Come up with more features as your pile of done tasks grow (if you find it appealing)! Is it easier to find accountability through a group of other people, or is it easier to fulfill tasks when it could be turned into a competition against other "players"?

Come up with useful and fun rewards!
Enjoy a snack! Get or upgrade a tool or equipment! Get to see a picture, or a quote, or a sound as you progress through your responsibilities!
