Great expectations.

When you woke up this morning, you will no doubt have automatically anticipated the what day ahead of you would be like.There's always something that fills us with a little bit of dread, whether it's seeing someone we don't want to, or facing some kind of challenge that we'd rather not.
A few days ago, after my expectations of being stuck inside the four constricting walls of University for five consecutive hours turned into a casual stroll around town, eating grapes and deepening my love affair with Lincoln, I was left with  a lot of time to myself, and my mind wandered, as it quite often does.
I got to thinking; grapes are so nice. Although, one of my more constructive thoughts was this -  why do our expectations of things always seem to be low? In my short 19 years of life, things have hardly ever turned out as bad as I first anticipated. I've just finished my first week at University this year, and after spending, quite literally, months dreading it, I actually loved it.
I read that roughly 90% of the things we worry about never actually happen. Which means I probably waste most of my life.
And of the remaining 10%, 9% of what we fear, occurs because we subconsciously concentrate on it and make it happen ourselves. So, reading between the lines, if you wake up dreading something will go wrong, there's a 9% chance  that it will. Oh the irony.
I habitually dread things before they happen, and predict the way events will turn out in a negative way. And my guess is that you're probably guilty of doing that on occasion, too, aren't you? Do we do this to avoid being disappointed? Or does having low expectations restrict us from having as much fun as we should?
Is it something we've learnt to do automatically? Although being excited about things is great, there's usually always a niggling thought that something will go wrong. 
I never seem to learn from it either, I would have thought that after years of things working out okay, I'd start to have higher expectations of life's hurdles. But I don't. I guess that anticipating everything in a positive way leaves room for disappointment every now and again.
When it comes to things such as job interviews or first dates, I can see how it makes sense to think of the worst case scenarios, so you're prepared, just in case. I guess the worst thing that could happen in any situation, though, involves falling over, dropping something, or getting toilet paper stuck to your foot. And if that's all that life can throw at me, the word 'resourceful' comes to mind...
