Make a list of what you want to do, in order of priority..
Then startingwith the item at the top of your list, sit down to do it for 10 minutes only.
Then walk aroudn the room for a fe wminutes.
Keep doing this for up to an hour, then take a longer break.
I find "bite-sized-chunks" works for me for work, study, learning etc.
I get put off when a task seems large, so break it down into manageable smaller tasks.
