I've got two numbers for you today.
The first one, 15, is called quitter's day in January. That's the day when everyone stops trying to pursue the resolutions they set for themselves on day 1. On the other hand, 22 is the number of days if you do something consistently that you could actually begin to establish a lifelong habit.
Just two numbers, but there's a world of difference between them.
God bless you!
