Find an amount of time that works for you and doesn't seem overwhelming. Like, maybe you decide I can work on stash sorting for 10 minutes. Just 10 minutes. Set a timer. I do that with Lightroom photo organizing. I tell myself 15 minutes. And if I want to keep going after 15 minutes, I'll do a few more. But if I stop at 15, that's fine. I did what I wanted. And I find that 15 minutes 5-7 days a week keeps it fresher in my mind than 2 hours once a month. So, for me, it goes faster because I don't have to remember what I was doing last time because last time was only a day or so ago. But that's what works for me. And it took a while to figure that out. I'm still working on them, but I've made a lot of progress 15 minutes at a time. You'll find what works for you!
