Another key part of this habit is to make some of your runs short and sweet! A quick 10 minutes is better than not running at all. Many times I get out the door to run 10 minutes, and after 5 minutes I feel good and stretch it to 20-30 minutes or more. Try this for a month and you will find your running will improve.
So try running everyday for a week, then take a rest day. Then stretch it to 10 days, before taking a rest day, then 2 weeks and so on. Once you develop the habit you will find it becomes easy to get out the door everyday!
