21 day theory

Have you guys ever heard of this "21 day theory"? Apparently, if you're trying to quit something or take something up, all you need to do is set a routine of sorts and follow it for 21 days and after that it will be a breeze. I was actually talking to one of my scholar friends Mario about this theory. See, I want to start running and living a healthy, active lifestyle and we concluded, through much discourse, that if I can set a routine for 21 days (or 3 weeks) then I should be fine.

Well, I actually think it makes sense. 21 days may seem long but in reality it's a little less than a month. However, I still think it's long enough to make a routine out of something. After the initial 21 days it'll feel like routine and i won't have to force myself to get up out of bed, put some clothes on and go for a run. I don't know how well this theory might work with quitting something though. Maybe it takes a little more work to quit.

Perhaps this "21 day theory" is actually subjective and depends on the person. For some it may take 7 days or 14 days and for others it may be 30+ days. I guess it really comes down to how bad you want to quit or take something up that determines your own personal "21 days theory". I'm proud to say that ever since I had that chat with Mario I've actually been running everyday. It's only been a week but I'm already starting to see progress in my stamina and to be honest, it feels GREAT!

So now I ask you: How many days is your theory? How long do you think it would take you before you can quit or make something a routine? Have you taken anything up or quit anything recently? I know what I want to take up and I've got my foot in the door. Now it's up to me to keep it on up and believe me, I will definitely keep you all posted!
