Giving a good habit 3 weeks

Going to try this creating a new (good) habit in three weeks. I should be a pro at this by now, but those ugly bad habits always come creeping back in. I think one of the problems is that change comes so slowly, and for someone like me, in this day and age who is used to instant gratification, the word slow is not often in my vocabulary. I have noticed that I do have some habits that I've acquired in the past year or two that could be considered an improvement on my former 'life' (non Mom, triathlete, soccer player and couch potato all wrapped up in one). Now I don't have time to be a couch potato, don't have the knees to be a soccer player and still desperately hanging on by a thread to being a triathlete while raising two kids! But I have to remember to be gentle on myself because change does come slowly, but it eventually does come. So I will try easing myself into some good new habits by picking 1 - just 1 and giving it three weeks. If it's successfull, we'll try another. So what is going to be good habit No. 1? Good question. Maybe it's to blog each day - just a little. Later, we'll shoot for the moon!
