I'm going to reschedule the start of the Challenge for this coming Monday. I'll get the forum set up for it this weekend.

One thing to think about is giving yourself a 100 step goal based on actions rather than on outcomes. For example, signing up 100 new players in 100 days is an outcome-based goal, and it might be tough to achieve, or it might not.

But creating 100 pages of content over 100 days is something that you definitely can control.

Another example might be losing weight. Losing 25 pounts in 100 days might be tough, but going for 100 hour-long walks is action step oriented.

Focus on the action steps instead of the outcomes, and you'll get the outcomes you want. (Provided that you've picked appropriate action steps.)
