I'm going to preform the easier chores now.
What about the difficult chores? Are those already done?
I'm already worn-out from doing difficult chores.
All the chores need to be done eventually anyway. The order you preform them in is up to you.
I would always prefer easier chores.
That is fine to do. Doing easier chores first makes it feel like you are getting a lot done, which can energize you for harder tasks ahead.
