I don't really trust myself with 'light bulb' moments.  While at the time I may strongly believe that I'll be able to carry out my plans, my momentum dissapates rather rapidly once the initial excitement is over. I did something tonight, which could take me back to square one with another 90 days ahead of me. While I strongly believe the literature that argues it takes approximately 90 days to break a habit, 90 days is not actually the norm. Perhaps that's why so many peopel fail. Now the light bulb moment has gone, maybe I won't think of it as having to be 90 days. I could do it in 3 sections. Three blocks of 30 days. The figure 3 most certainly appeals to my fascination with the number 3. When I wake tomorrow it will Friday 15th July. That's 5 lots of 3. Silly as it is that a number should mean something, it makes it a very appealing date to start, or at least try something that always has the potential to make or break me.
