Comes from within. I've had times in my life where I was broke, no job, woman, nothing and I was happy. Other times I was making more money than I imagined, had a "purpose" and got laid almost every night and was completely miserable. I learned that it is not what you have or don't have in this world, not even what you do that determines happiness. It all comes down to yourself and I know that sounds oversimplified and cliche but that's it. One time I wound up jobless, homeless and nothing to show for and it turned into the greatest adventure of my life. Sometimes the struggle, digging yourself out of a pit, it can really show you what you are capable of.
