There's a reason I test myself with 30 Day Challenges every month. It's proven that doing something for 21 days straight commits to memory enough to become automatic.
Think about that for a second.
No matter what it is that you feel you are doing incorrectly or avoiding altogether, you can reset right now and start fresh tomorrow.
All you have to do is do.
And then repeat it the next day.
And the next day.
It only takes 21 times.
After three weeks, you won't even have to think about what it is that you improved in your life. It will just be automatic; second nature to you.
