I often feel that Passion cannot hang around for long without determination and blind determination is it's closes ally. To live and work with passion is to keep a thing focused which wants to wander, like a pesky pulling dog on a long lead.
I think modern persons idea of 'finding' passion is fed by the very thing that also 'keeps them from it' which is being plugged in and passive on things such as tv etc. And in a way that exists to keep then looking and feeling just out of sorts enough to need to look more but also to satiate this loss of 'passion' with 'shopping therapy' and eat, drink, and watch.
Sometimes people expect happiness where it cannot exist. To find happiness and passion, we have to walk through sad and boring sometimes.
Most people don't have the will to make it through the sad and boring for long enough to come out on the other side and find the love of their life. It is much like the approach to relationships these days, if it gets boring - swipe for another...
