The thing with putting up post-it notes is that they can be very addictive and entertaining. I personally some friends of mine that, due to their busy schedules, opted to put up a lot of sticky notes on to their organizers, their notebooks, and practically anything that they come into contact with.
It seems that due to the busy schedules, they put the responsibility of "remembering" their tasks to the post-it notes, who are otherwise unaware of what it is made to do. Their owners love them, so that probably makes it a whole lot better.
On the contrary, this can be very stressful for some others who only want some peace of mind and less stress at school, at work, or at home. These people see nothing but work, work, and more work once they notice the array of notes sticking to the walls of their place.
Now that would be very sad for the innocent stick-on note, wouldn't it? The note knows nothing about its owner's stress and problems, and yet it is dragged on to the situation. How can it be possibly happy when its owners is under fire?
I'd say give them a happy face and everyone will end up cheering. Pin your notes with one of these wall magnets, featuring a smiling noseman. Not only will that cheer you up, that will also brighten the day of your duty note! So go ahead, give it a try. Put a happy tone to your task notes and you'll see yourself accomplishing them with a smile.
