Rubber stamps are your friend
I have two ways of tracking the various little things that I want to accomplish every day:
Method 1: Choose a stamp (or sticker or whatever) to represent the thing that you want to do; do the thing and then stamp that day's calendar page to show that it was accomplished. This method is good for tracking activities, but not good for reminding yourself to do something.
Method 2: I have a custom message stamp that comes with two stamp plates - 4 lines each. One of the plates is dedicated to my daily checklist - up to 4 items that I want to do each day. I then stamp each day's calendar block for however many days that I want to remember to do the activity. If I want to establish a new habit, for example, I'll stamp the next 30 calendar blocks. Each day when I look at my calendar, I see a reminder of whatever I need to do; after I've done it, I check it off or scratch through it. The custom message stamp was less than $20 at OfficeMax, and I've already found 25 different ways to use it.
If you're using a digital system, why not just set up daily recurring tasks? No matter what system you use, either you want to do these particular things each day, or you don't. If you really do want to practice a unit of piano each day, go ahead and put it on your calendar - at least until it's become an established habit. I've found that this is the edge that I need to go from wishful thinking to action.
If the tasks don't really matter that much (lean more toward wishful thinking) or if you just want to make sure that you do it at some point during the week, put them on your NA list.
ETA that I think a printed daily checklist is also an excellent idea; it's just that I'd rather not use an extra sheet of paper for something like that. My planner is already stuffed as it is!
