Getting enough sleep.

Arianna Huffington was right. Sleep is absolutely necessary. In addition, some people require only 4-5 hours of sleep, others like myself require 7-8 hours to be "good". Getting a FitBit to track my sleep has also been helpful. Just because I sleep on time, does not mean I have "enough" sleep. Most of us don't fall asleep until 1-hour after we lay our heads. And in addition, most of us do not get enough "deep sleep."

In addition, after I started tracking sleep, I realize caffeine has been detrimental to getting "deep sleep." I often switch to decaf or go cold turkey to help my body detox from caffeine.
