Here's how it works. One day, when I'm wallowing in bed or perhaps killing zombies at some ungodly rate, I spring from my lethargy and try to make a realistic-ish accounting of what I'd most like to and be able to accomplish in the next week. The one I'm using right now (started yesterday) looks like this:
On five occasions, do each of these:
Meditate (10-30 minutes)
Get 5 fruit and veg in a day
Maintain friendships and/or practice kindness
On three occasions, do each of these:
Study ancient Greek (30-90 minutes)
Draw (30 minutes)
Study music (30 + minutes)
Study for GRE (30 + minutes)
Do other writing
Get other exercise
Work on house (60 + minutes)
Read to prepare for school
They're all listed out in a notebook. I put a star after each thing as I do it. If you'll notice, I have (5x6) + (3x9) goals, which means 57 total. I'm shooting for ten stars a day and a day off. The list doesn't include other basic things which better'd damn well get done regardless, like shopping, cooking, cleaning, watering the garden, etc. They are the things which I tend not to get done, or which, being done, make it so that other things naturally happen. Here's the best thing: I don't usually make it through a whole week with a list, but it still mostly works.
Anyway, that's my secret bullet. Until I get bored and invent a new one, anyway.
