Find the Melody
As a species, we feed off of our surroundings. The uglier, more hateful, negative, etc. they are, whether internally or externally (or both); it affects all of us. Think of it this way. If a child grows up in a home where there is only loud arguing and violent outbursts, etc.; he/she will carry this with them throughout their days (and at some point, will more than likely, act out in a similar manner). Our nurturing/surroundings create our physical, mental and spiritual being.
Note: Song intro/backing/outro is a song I've written titled, "Imagine a Day".
