I track my progress in lots of ways. It might make more sense to just pick one but I like how each way emphasizes different parts of my creative habit. I use two tracking apps on my phone. I use the habit list app which lists all the habits I'm working on...that includes the super boring stuff like flossing my teeth. This one is a great app if you have a list of stuff for every day.
I also use the collect app where I save my photo from each day. This one is much more visual. I love how all the days look together. Looking back through the months on this app helps me to see this project as a whole.
In my studio I have Elise's habit tracker. I bought the digital download version of it so the great thing about that is you could print out one sheet for each habit you're working on. This method has sort of a 'gold star' feel to it. When I color in that circle for the day, it feels like I've really accomplished something.
Also in my studio, I have my stacks of paintings. It's fun to see the pile grow. When I find the energy, I'm going to hang them on the wall above that shelf in a grid formation. I think that'll be a good way to reorganize them into mini series and give me ideas for what to paint next.
Then I have the gallery page on my site. I guess I'm pretty obsessed with the whole grid and repetition thing because I really love this method too.
I'm not sure that I'd recommend tracking in five different ways but I think you find ways that work for you. A few of these methods (habit list, collect app, Elise's habit tracker) really encourage me not to miss a day. Some of the methods (collect app, piles of artwork, site gallery) really help me focus on the big picture.
If I was to recommend a system, I'd say make sure you find one that does both for you--encourages you not to skip AND focuses on the project as a whole. If it's also easy and enjoyable to maintain, then you've found the one for you.
