When something becomes routine, it is woven into the fabric of your life.  It becomes an unconscious part of each and every day.  That's why you want good things to become habit or routine.  Unfortunately, when things fall out of your routine, they are easy to disregard.

Last month, I got out of the routine of updating this blog each day.  Before I knew it, a month had gone by without updating.  Every day it gets easier and easier to not do what you know you should do.

There's no magic Elf dust to make this easy.  It's just making the right choice each and every day.  No matter what that choice is — eating right, exercising, tidying, making the bed, cooking instead of grabbing takeout. 

Whatever it is, keep at it.  It's the only way.
