Some sources say it takes 21 days to form a habit, some say it’s 24 days, some say it’s 30. Doesn’t really matter. What matters is that you do not need to commit yourself to waking up early on every day till the end of your life. Just commit to wake up early for … 3 weeks. That’s all… Yes, building a habit takes some time, but 3 weeks will be definitely enough for building basic early waking up habit.
It’s no surprise that you don’t feel comfortable committing to waking up early every day until the end of your life. Indeed, this kind of commitment is extremely hard to make! Well, by committing to 3 weeks only you make it much easier on yourself. You know you can quit it on 22nd day and start sleeping for as long as you want again. But guess what? After 3 weeks, you will not want to sleep any longer! Once you make it a habit, it sticks and it’s easy to follow. It’s easy because you know you don’t have a lifetime commitment, and you can break it should you feel like it.
