Since you want to do more, I know this sounds crazy. But when I set up a personal kanban system, it really changed my life. You establish a backlog of what you want to do. Then you limit the amount of work in process (WIP). That gives you a very small number of open tasks to switch between, which means you end up increasing your focus and being forced to finish things. (Or at least clearly admit that you're quitting a thing.)
This process is, honestly, pretty unpleasant at first. Being a passive consumer pays off right now. There's always a new article, a new tweet. When you're bored, you just skip ahead. Real work is frustrating and pays off very slowly. So you're going to spend months just breaking yourself of your quick-entertainment habits and learning to put up with the frustration of longer scale.
If you really struggle, consider trying out the pomodoro system, which involves fixed periods of focus with breaks. E.g., 25 minutes of work with 5 minutes of break. When I'm feeling really resistant to production and just want to fuck around on the Internet, I'll tell myself, "Ok, one pomodoro of work on the project." I'll set my countdown timer and just fucking do the work for 25 minutes, no matter how much I don't want to. Often after that, I get into it and it's fine. But that first wall of resistance can be brutal.
The other thing that really helped me is taking up running. Pick a race, like a 5K. Train for it and do it. Then pick another race. The main trick to running successfully is not giving up. You learn to put one goddamn foot in front of another. Some days it's a joy and some days you hate it, but that ends up not mattering so much. You slowly learn that your feelings are just these things your brain does. You can notice them without having to obey them.
+1 my wife and I set up a kanban board in our house for tasks we needed to accomplish so we could easily see each others priorities and current efforts. It was game-changing. We are able to get more done with much lower stress.
++, I'm in the middle of a project that was supposed to be a quick 2-3 weekend deal. It's now taken much longer than I originally hoped, and I'm constantly tempted to give up/set it down for another few months but I know I just need to reformulate a plan and finish it instead of starting other things and having 2-3 half assed projects.
You can happily use, e.g., sticky notes on a wall by your desk or inside a cabinet door. If you really can't do that, software can be ok, but it's easier to develop bad habits with software. With a physical system, certain things are usefully hard.
When I'm starting someone out, my standard columns and WIP limits are:
* to do
* soon - max 5
* on hold - max 3
* working - max 3
* done
The "to do" column is the backlog. "Soon" is the things that I'm doing next. When I start on something, it goes in "working". If I'm blocked on an external dependency, it goes to "on hold". Items never go back to "to do".
When I've finished an item and want to know what do to next, I'll first look in "working", then "on hold", then "soon". If all of those are empty, it's time to think about strategy for a few minutes; I'll look at everything in "to do" and promote a few to "soon".
Hopefully that's enough to get you started. The important to remember is that the board is supposed to mirror (and shape) how you think about the work. If somebody happened to randomly ask you "Hey, what are you working on now?" it should generally be what's in "working". If somebody asks what you're doing today, it should be the stuff that's in "working" and "soon".
If you have different categories or WIP limits in your head, that's fine, go ahead and represent that accurately on your board. But every month or so look at the board, think about how you work, and tinker. E.g., I might say something like, "Things felt really chaotic this month, so I'm going to try dropping the WIP limit on "working" next month.
As cotsog says, there's a whole personal kanban literature. I personally haven't read any of it, but I hear good things.
One tip, though: Be careful of focusing too much on the theory.
In my experience, a lot of task management methods fail to take root because the person is supposed to follow the system. However, the system doesn't really fit the person, so what is begun in hope ends up gradually falling apart. Doing a kanban approach right is about paying close attention to what's actually going on and then tuning the system.
As an example, take WIP limits. When I start teams with kanban approaches in work settings, they often want to pick high WIP limits, because a) they currently are doing a bunch of things, b) it seems macho and achievement-oriented to have many balls in the air. But they also want to follow the system, which says "minimum WIP". So they will either pick a high limit, and so get no benefit, or pick a very low limit and get frustrated with all the chaos that a big process change causes.
The approach I instead suggest is to just lay out the board to match what's really going on. Inevitably, they have a lot of WIP, so that's what the kanban board should show. If that's 10 things, it's 10 things. They agree that's a lot, so we might set a WIP limit of 8. If that works, we'll drop it a little more. And then again. At some point, it will get uncomfortable, and that's when things get really interesting, because it's exposing a problem in the workflow. Do you change the WIP limit back? Or do you say, "Hmmm, how can we remove the blockage?"
There's no right answer, really. It's about paying attention to the details of the work and your experience. Kanban boards aren't really a solution. They mainly make your workflow visible so you can notice problems and fix them. The magic isn't in the board. It's in your willingness to iterate.
WeKan is a free software KanBan program like Trello, and is what powers https://todo.cyphar.com (I even have some boards public so I can show people my priority list in projects I maintain)
