Tax return (groan).Tonight get out all the paperwork and put it in the middle of the table. Easy.
In the morning read it and decide on the next action. Painless.
Later, do the next action - no problem, no stress.
Now sometimes I just go along in baby steps for half an hour here, 10 minutes there, over a weekend say, or even a week if I've got a lot more interesting things I want to be doing. But sometimes I realise there isn't really that much to it, and if I just focus for an hour or two, it could be done and off my mind for another whole year, so I just...do it.
