You have to believe in something. Deeply.
I believe that at all times, we have to have full steadfast belief in something. Something greater than ourself, something that we'd bet our life on. without this, there is no guarantee, there is no direction, there's no future. Whether it's a belief in God, yourself, the system, process, someone else, gears of the technological ascendance turning, or whatever it may be, you have to be able to put your full head towards something.
without this, we're simply put just lost!
