1- Whenever you finish working on something, put it away.
2- Never leave the office without cleaning your desk and leaving things organized for the next day. Combat paper proliferation by dealing with each piece while it is fresh in your mind.
3- If time constraints make this impossible, carry the paper around with you until you can give it your attention. Look at it, define the problem, devise a solution and then take action. But do not let things sit and build up as a testament to your indecisiveness.
4-“In” and “Out” trays can be helpful if you use them. If you do not make use of them, they
will become just another place to accumulate paper. Let the trays help your work flow.
Empty them on schedule, daily or weekly – or get rid of them.
