Want a great time saver for your work and personal life?  Try a solution promoted in the GTD methodology: the two minute rule.

When processing your inbox any action associated with an item that will take two minutes or less to do should be done immediately.  This is because it would take more time to organize the item in your system then to resolve it straight away.

The two minute rule has some flexibility.  For example, if you have lots of time available for processing, extend it to three minutes or more per item.  If you have limited time, reduce it to a minute or ninety seconds per item.

In the end, some actions are best done when they first show up.  That is why completion of two minute items leads to less stress and more success in your work and life.
