It's about choices, and how we choose what we choose.
Like, finding a book you've searched for for six years.. opting not to get it because the rent is due. And books are about the only things I can honestly say I am addicted to.
It's not what we want that makes us happy; rather, it's what we need. The feeling of sadness is quickly subdued by the great and awesome feeling that one has made a choice not out of personal desire, but out of necessity and of understanding how life works. Life works in the long-term, and not in short-term gratifications.
Perhaps I have taken one step forward to leaving my childhood, teenage, and 'young adult' years behind, to welcome the next chapter of my life as a grown man.
