For some reason it has become extremely important to save time and always be occupied with something work related. Somehow it reminds me of an old method to look important at the office. Basically you grab a piece of paper and run around the office. Your boss will see that you are constantly in movement and will think you are doing something important.
Unfortunately 99% of us, the human kind, can only be efficient for a few minutes. Often less than one hour at a time. Because of this it does not matter if you learn how to tie your shoes 3 seconds faster.
I am not able to find a source on this one, so feel free to quote me:
A task will always take as much time as you have available.
Sure it is a good idea to save a few seconds but instead of spending time trying to figure out how to save time I recommend you to find your distractions and simply remove them.
By eliminating Twitter, instant messaging, Facebook, forums and similar distractions you will find yourself being more efficient and therefore getting more things done within the same amount of time.
Thanks to this method you can get all your work done during the day and still get time to play with your kids and be together with your family.
