Sometimes we need to think ahead and balance our time in such a way where we put off things that we know are going to get done almost regardless of circumstances (mostly) for things that are important that can only be done when we put time aside just for that thing.

For example, I just put off vacuuming the living room floor because I know it's going to get done eventually, so that I could set time aside to draft out an experimental education system I've been developing, something that I would probably only have started if I put time aside for it.
