My habit is waking up by 6:00. I was working on getting up at 7:00. That was pretty regular, so I thought I would try 6:00. I am so much more focued and productive in the morning. So the earlier I get up, the more morning I have. This has also helped my exercise routine. I was regularly exercising 3-4 days a week, but now its 5-6.
So far I am on day 6 of waking up at 6:00am. I am determined to go 30 days in a row of waking up at that time to seal it as a habit.
