Taxes: Instead of writing down “do the taxes” on your to do list, break it down into smaller, easily achievable steps. For example, gather the paperwork. Then, add up the total income. Next, add up all the deductions, etc.
Declutter an area: Instead of writing down declutter the garage for example, break it up into go get all the garbage out. Then, find anything that doesn’t belong in that area. Next, start grabbing clutter that you are ready to part with, etc. Or maybe even more specifically, set the timer for 10 minutes a day per step until that step is completed.
