If you have stacks of laundry, papers, tools around your home and you keep avoiding them, find the smallest number of things that you can do. The smallest number that when I suggest put "x number of things away" you say "Sure, that's easy, I can do it right now."
In my house, that number is 5. I can put away 5 dishes after I pour my coffee. I can do 5 things while the ref figures out whether the defense was holding or not.
Setting the goal very low means that I can do it quickly, and setting the limit no higher than 5 means that the chore will not overtake my day. My entire Saturday won't be taken up by chores.
Is the work all the way done? No. But is it a little bit better? Yes. New goal: making things a little bit better. You can build momentum this way, you can be proud of yourself when an old, annoying task is finally done.
