Feeling a little blue in January is normal.
I eat all of the time... at least five little meals a day.
I took anatomy classes. I went to medical libraries and talked to doctors and nutritionists. I did the whole thing before using myself as a human guinea pig.
I always say centered food equals centered behavior.
However, don't let perfectionism become an excuse for never getting started.
Everyone thrives most in his or her own unique environment.
