Reality is the brick wall placed strategically on the path to our dreams. It is our duty to find the way around it, to make it to the end of the road, to persevere and accomplish what we want to do in our lives.
Some of us do it, but that other ninety percent is stuck with a job that isn't fulfilling to their life. And in theory it's that exact job that drags us down, introduces us to that mid-life crisis.
It's up to us to be happy with what we've made of ourselves. It's in our genes to want to be happy, and strive for perfection in our life.
You never really know that you're happy until you know when you're unhappy.
