A few adjustments to daily life mixed with discipline can reduce the ugly blues monster and put everything into perspective again. When the blues hit, let them. Spend some quiet time and contemplate without being negative. This aspect of human nature, which calls for analysis of the past, does not have to be a negative experience. It is simply a way to examine personal history and make sure you stay on, or move toward, the right track.
Spiritual health is the most difficult to understand and maintain.
With the increased communication and tolerance in the world comes a blurring of boundaries. If a person is too strict in faith they tend to become isolated to like communities. If a person is devoted to tolerance they tend to generalize their faith to the point of non-recognition. Then double-talk can easily undermine the connection to spirituality. Balance here would equal strength or determination.
