I can't do any of the todo-list stuff after work, for the basic reason that it also feels like work when done this way. Also I usually spend too much energy at work so afterwards I don't have any left to motivate myself etc. Ergo: Zero effort or it won't be done.
So the first thing I do is I put reminders where I see them. For instance there's a contract for a telephone provider I need to quit. The box connected to the provider is laying right there next to the computer I'm typing this on. This way it gets into my head and if I don't have higher priority tasks I will think about it regularly, without ever actually pushing myself to it.
Then instead of already resolving the issue (which in itself would cost energy) I procrastinate by planning or doing simple steps toward the goal. In this case it may be checking out on the website of the company how their quitting process works. After that I feel like I achieved something and successfully avoided doing actual work at the same time. That's the best reward for doing part of the job, feeling like you cheated your boss (in this case your inner moral guard).
And when there's really not anything left it most often means that the last step really isn't any effort anymore. So when I have everything prepared I just need to write a short text, and send it to the company, and be done with it. Because everything was planned out and prepped already.
Last but not least, if I really can't convince myself to even do a small step like googling the website of the company, then it probably means I'm too exhausted and instead of doing any serious tasks I really should take a walk and a nap, which I then also have motivation for since it also avoids doing the painful highest prio task.
Yeah, it's a slow process, but it actually hacks your brain into doing real work while it thinks it's procastinating, instead of the other way around.
