Take the first idea that you have written down from the idea brainstorm you did earlier. Now apply the IDEA Criteria to that idea. Then decide if it is an idea that is worth moving on now, later, or not at all. Mark that down next to the idea by using a checkmark to represent moving ahead now, an arrow pointing right to indicate you'll work on it later, and an "x" next to the ones that aren't worth moving on at all. (You could actually just cross out those "not at all" ideas altogether -- which would be even better -- but if you're not comfortable with that yet, just go with an "x"...for now.)

Continue doing this for at least ten ideas on your list. You can keep going until you've applied The IDEA Criteria to all of your listed ideas, but do at least ten for now. You can always do the others later.The idea (pun totally intended) here is to build the habit of using the IDEA Criteria for each and every idea you have from now on.
