Stop. What are you doing right now? You're reading a blog. (mine!)
Forget that. My blog isn't even that good.
A better question would be "What should you be working on right now?" Think about that for a moment. Better yet, eliminate all the "should do" things. These are things like mowing the lawn and doing laundry. Sure, they need to be done but they won't have a lasting impact.
Find something major to do. Think big. What's a giant problem facing your field? How could you make a measurable impact on that*?
Plan out your first few steps. Don't be afraid to let your imagination run free. Create a trickle list of activities that'll let you move closer to that goal.
Do the laundry but work on the big stuff now. If you don't, when will you?
*Yes, the average CS guy probably won't make headway on P=NP. There are plenty of problems. Be creative.
