My Outlook on Life

I'm told there are two ways to look at life: everything is random, or, everything is connected. I myself have never given much thought to the issue before. There are times when I do believe that everything is connected by some invisible thread of fate, and there are other times when I think that we are alone in this world, that there are just coincidences, and that not every little encounter has an impact on our futures.
Those thoughts of being alone are probably just brought on by those random times when I wonder what goes on in everyone else's minds, and I realise that I don’t know as much as I think I do about those that are close to me.
So I’d have to say that I believe that everything is connected. When I think about the millions of people on this earth and their lives, I can't help but imagine the Moerae (the three sisters from the Disney movie Hercules, who decide human fate) and their pieces of string that represent the individual lives of humans. I imagine all our lives as a big ball of yarn that's managed to become tangeled together. While I do imagine that everything in life is connected, I do not believe that it's predetermined. I think that every choice we make, and every person we have the pleasure of making an acqauintance with, has an impact on our lives in the future. It is my belief that our lives are shaped by the lessons we learn from our own experiences, and those that are taught to us by the people we meet.
Part of the reason I think this way about life is because of all the times I've heard theories about alternative universes. Just imagine if there were alternative worlds where different versions of us went through the same experiences we did, living through all the different scenarios of 'what if' we've all asked ourselves at some point or another. I think that would truly be something worth seeing if it were true.
I also don't believe in predetermined fate or destiney because who would've been the one to determine the path our life leads for us? If there was such a person, I don't think he, she, or it would have the time to personally plan and plot out several million lives. Besides, humans are unpredictable by nature; what if one of us threw a wrench in all the planning? What would happen then? Surely our lives couldn't all be that dependant on each other.
