Leigh Pretnar Cousins, MS, is an educator, counselor, writer and speaker. She has a blog with PC entitled Always Learning. The first of the twelve days is here: Day One: Attention is everything. (Twelve Days of Wisdom) | Always Learning

Cousins uses a quote to tell us:

…the information we allow into consciousness becomes extremely important; it is, in fact, what determines the content and the quality of life. -Flow, pg. 30

The articles are not lengthy but I found them useful, especially with the additional resources Cousins references.
