I've been using a simple solution for several years now.
Here's the trick.
Clear Your Desktop!
I've got you there, haven't I? Because you don't know whether I mean your real desktop (made of wood) or the screen that faces you as you read this.
I refer to the screen that faces you as you read this.
No wait! There's more
Most users I see have a screen desktop that is a vast un-navigable array of icons. There are shortcuts and there are documents, and I get paid $100 per hour to sit while they mutter "It's here somewhere".
"A place for everything and everything in its place" was a motto my mother never taught me; if she had have done so, my early life would have been a great deal more pleasant.
I had to learn the hard way.
Make an effort, today, to start filing things on your hard drive in a logical pattern - client data in a subfolder of "Clients\", personal data in a subfolder of "Personal\".
And stop storing data on your boot partition (drive C) in that "Documents And Folders" thing. Drag everyone of them to your data partition (probably drive D) and stop using your desktop as a landfill site.
Use the QuickLaunch toolbar for those tasks (programs or documents!) you use throughout the day.
Then your desktop will be as tidy as mine:-
Here's the 1-Step
At the start of the day, make a shortcut icon to ONE, and only one task that should be completed before the end of the day.
Just one. Not two.
That icon will remind you that there is a priority task.
And it will get done.
Tomorrow is another shortcut!
