All true, but worth noting that sometimes making that to-do list is the first step to doing the thing because picking the first item off the list and taking 10 minutes to do it is doing the thing. If you aren't doing the thing because it's a monolith in your brain that is going to consume the next 6 months of your life and you're paralyzed by its enormity, salami slicing 10 minute chunks off the front of it can be a good way to get started.
