The first thing I define when I create a control flow structure is the 
default condition. Set it up with the test and empty brackets, set the 
default action, and then go back to fill it in.

A strict default action can go a long way towards letting you code what you need now to make progress, while leaving the rest for later. I see too many coders take all day to try and accommodate everything when all we needed was A and B (for now). 

Code the default case. Protect against anything that is not what is expected for A and B, then code A and B and move on. 

Sure it will fail for tons of situations, but it will never let you down for A or B (and that is what I asked for ;-)
