That's the funny thing with life - the yellow brick road looks glamorous, but the road itself is built from the bricks of disappointment, failure, sadness and anger. All we can do is get our heads down and keep laying those bricks, even when it sucks most - because the truth is, that road we build with those same bricks, is the only way to actually get to the Land of Oz...
We're all here, building that same road. You are NOT as alone as you think. Job went through it, Jesus went through it, even the happiest people who walk the planet went through it. The trick is to not give up - not ever, especially when you're just about to make it. (Which is when most people seem to throw the towel in, sadly.)
