Destiny Calling

I have been thinking a lot lately about destiny. In my own personal and self created spiritual beliefs destiny plays a big part. As most of you know my 24th birthday is approaching at rapid speed. And today I was thinking hmm when is destiny going to call me. What if he already called and I was on the phone and my call waiting didn't work so all he got was a busy signal. Will he call back later? Or is destiny a one shot deal?
Better yet what if in my short 24 years I have already fulfilled my destiny and it is unannounced to me? Now I am just a dog chasing it's own tail. I am searching for that which I already have kind of like when you rip your entire house apart looking for car keys only to find them in your pocket. If that is true, that I have already fulfilled me destiny should I feel cheated? I mean what the hell am I supposed to do with the rest of my time. I am not saying that I have, this is simply a what if question.
I am almost 24 and I am really starting to search for a meaning or purpose to all of this. I am too stubborn to believe that this all random events with no connection to a larger picture. But what if I am just fooling myself and destiny is a man made notion like money. What if everything we strive for is simply a creation of our own minds imagination. What if hunting destiny is just like hunting Big Foot. That in my opinion is almost more scary then missing the call.
I recently read a blog where a man said that he was doing God's work. This got me reevaluating my own beliefs. At first I was envious of this person because they were so certain that they had it all figured out and they knew exactly what they were doing. As the only member of my faith (and this statement is true because I am the creator of it) is it possible that I am completely wrong? But this leads me to be forced to explain my concept of religion. I will make this brief, but I feel that at the very least you will get a good laugh out of it.
To start when I was in my teens I went through a period where I felt that I really needed faith. This led me on my "church search". I went to just about every religions church or wooded area attempting to find one that I could give my full blind faith to. I never found that place. But frustrated because I wanted something to believe in I decided to evaluate my life and base my beliefs on things that I believed to be true.
First I guess I should mention my higher being. I sometimes refer to it as God because there is no other way of stating it without confusing people. My God is a great being. It doesn't care if you believe in it or not. All it wants is for you to fulfill your destiny. Destiny is a tricky thing though, your destiny could be something grand like saving the lives of others or it could be something sinister like taking the lives of others. Your destiny is your own and you decide whether or not to follow it. If you do follow it then your soul moves on to another place, if you don't then you are recycled and given how many ever chances it takes for you to get it right.
See simple enough. I will stop there because after that things become a little a tricky and to some a little freaky. The whole point of any of this was to get you all thinking about your destiny. To remind you to listen to that little whisper inside yourself and to use you call waiting because you never know who might be calling.
