which way please

today i sat contemplating many things. one question that keeps me occupied in thought is, are our destinies predetermined? or do the choices we make everyday alter the rest of our destiny? we have free choice and will, and some will argue that God ultimately knows what we will choose thus our destiny would be predetermined, but what about changing our minds? was the original decision the right one, or the second one, or maybe when we switched back? if i choose something really bizarre tomorrow, out of character even for me, would that have been predetermined, like if i decided to buy a cowboy hat... not likely to happen but i could decide that i'm sure? not too sure... and i would really like the chance to treat life like one of those choose your own story story books, where you can cheat and read all possible outcomes and then decide the one you like the most.
