The U.S. Small Business Administration's Small Business Week kicks off today and runs through May 6, 2017. What better way to start the week than to adopt some effective productivity hacks? These three simple tips will give you a surprising productivity boost:

1. Take a look at your to-do list and apply the "worst first" rule. Find the thing that you're least looking forward to doing and get it out of the way so it doesn't sap your energy as you worry about it while procrastinating.

3. At the end of your work day, when you have the clearest vantage point about what needs to be done tomorrow, pick the two or three key things that need to get done.
