Somewhere, over the rainbow

Do people ever find their rainbow?
Are these make believe stories told to give us hope for something better? That though it hurts and everything's just turned to shit, don't worry - cause you're just one step closer to your rainbow! When? 
What if you've just accidentally walked straight past yours? Or what if you've just walked away from it? Then what? Do you get a re-run or a take 2? Or is it just tough cookies? 
Then i think of all the people that never find theirs. What if yours is all the way on the other side of the world? What if mines in Greenland? Should i go to Greenland just in case? What if you're too poor? But what if mines moved to Hawaii by the time i get there? How will i know that Hawaii must be my next stop? Do you have to just go without?
What if you find your rainbow, but your not their rainbow? Does that even happen? Or is it just a case of mistaken identity - on either behalf? What if it is a mistake and you never let go if it and your true one has just walked right on by? What if you were mistaken and walked away and you never get it back? How is that fair when both parties miss out? 
What if you spend your whole life searching to finally find it and then die? Do you die happy? Or die pissed off that it took you this long then you carked it? What a load of crock.
I hate all these 'half glass' analogies. I hate more that I'm one of the idiots that see it as 'half full' until proven otherwise. It's like I'm one of those douche bags that need to feel it for it to be true. How annoying is that? One of those douches that doesn't get why everyone else isn't a 'half full' sorta person. One of the douche bags that doesn't like these what ifs and coulda woulda shoula's when theyre so easily argued either way. What if it works/what if it doesn't? What if this happens/what if it doesn't? What if i decide this is what i want/what if i decide this isn't what i want? what if i feel differently/what if i dont? What if noone comes/what if everyone comes? what if i mess up/what if i dont? what if this is my calling/what if this isn't? What if i find something better/what if i never do? what if i was wrong/what if i was right? What if i regret this/what if i don't. What if, what if, what if.

Life's a bitch, i'm not sure why i keep forgiving it.
