As a Life Coach and Motivationl Speaker I hear a lot of talk about multitasking and STRESS.....
Multitasking can literally cause stress. Due to the amount of time multitaskers take to flit between one job and another, they become less efficient and their brain literally slows down. So now we have a situation when all the tasks have not been completed, due to the brain slowing down, which causes stress levels to rise, which in turn leads to mistakes being made and stress levels rise even more. So it's no wonder that we feel frantic when we try to do too many things at once.
Tip to combat stress:
Clear your desktop
A great clearing exercise is to clean up your desktop. Get those pdf files in one folder, get the word documents in one folder or categorize them and put them in a folder. Be sure to give your files good memorable names so you can search for them in the future. Don't name a file '1' as you will never be able to find it again in a year's time, give it a proper name like 'stats for week beginning 24th august 2009' and name all subsequent, similar, files in the same way. Put all your downloads into one folder as well so you don't clutter up your desktop.
