You just need to switch of job, if you don’t feel rewarded when doing it then it’s just not the right fit for you. And even then, something fun can become boring later on.

I know electricians for instance who love doing their stuff, so they have no issue in being motivated, while they were a mess in their previous work field.

And vice versa.

It’s not always possible of course, but the solution is not to ‘gameify’ your life, it will only work for a little while before getting bored of it.

And for the « home » task, I believe it’s more of a routine. If you know every Saturday morning will be to clean the whole house, you just do it without thinking much.
