Destiny is predefined yet controllable!

It does sound contradictory, doesn't it? Something that is predefined, yet controllable and prone to change-all the time! I am talking of destiny here. The thought sprang from the teaching that we all have our destinies, decided by, who else, but God!
I am coming to believe that God, or whoever the superpower is, that created us, that is if we didn't create ourselves, played a multi-layered game with us. He, or she, gave us more than we are made to believe. And the example of destiny, its variability and rigidity, an apparent paradox, is a beautiful example in this case. It can be life altering if you understand the underlying grandeur.
We have all heard of us having the power to shape our destiny,etc.. But a scientific explanation eluded me. I think I have found it. Read on to find out what I thought.
What we have been taught-The Traditional Wisdom
When we have been taught that each one, living or non-living, has a destiny of its own and we have no option but to live it through. We are made to believe in the all-pervading power that has taken the decisions for us-and for our own good. To me it brought a feeling of futility of all that happens around me, and more so my contribution to it. Well, if God, lets call the superpower by that name for the discussion, has decided me to be a super rich man-so be it. I will be something someday, and if he has taken the decision to make me that rich, he might as well do the work to get me there. Let me retire and enjoy my life.
What I think-Thoughts of a mind
Only when I thought it over did I find out the greater truth, whether it is a better truth or not, time will tell:) And this is how things come across to me- destiny is predefined, yes. But God has decided it only indirectly. More importantly, it is we who decide it directly. I will tell you how God has played the game and reserved the right to change one's destiny.
My scientific explanation
We all know of the awesome power our subconscious mind holds. Actually, our destiny is nothing but a future our subconscious mind sees for us. Don't you, the inner YOU, know THE truth? How many times have you lied or how many times have you escaped the wrath of your conscious? Deep down we also know the universal truth-what goes around comes around.
Our thought patterns, our beliefs, and our decisions form our conscious and our subconscious feeds on this conscious. The subconscious mind then decides where we would be lead according to our current action pattern. Eg, it would 'decide' how our kids would treat us by understanding how we treat our folks. How often have you seen an ill-treating child grow old to be treated badly by his own children or someone really important to him? Our subconscious mind, thus, guides our conscious mind to our 'destiny' that we ourselves have created with our thoughts and actions.
The colours in the picture called our life are for you and me to chose-lets not give it away.
How do you chose the colours?
What gains critical importance then is what are we choosing for ourselves. It was truly an eye opening moment when I realized that my actions, my thoughts, and the decisions I take in my mind- some visible to the world and most them not-will shape my life. It felt like being in the proverbial position of sitting on a pot of gold and begging for alms.
Understand this-and trust me it is the truth- anything that crosses your mind is half the reality. Remember that everything happens in the world twice over. It happens in reality, the world, as we call it. Then it happens in our minds. For example, if a glass breaks at your home- you may have witnessed the event or be absent from the place when the event occurred. If you were there then, the glass broke in the world and it broke in your mind-both at the same time. Since your eyes give you approx 80% of your sensory inputs-it becomes very easy for you to accept it as being true. If, however, you were not present at the site when it happened- it wont be a reality till it is recreated in your mind. The recreation may be initiated when you find it missing and ask for it and you are told that it broke. Immediately your mind creates a picture of the event and how it might have happened. Now, depending on the value-material or emotional- you decide to accept the thought or deny it. People suffering depressions at the loss of closed ones are unable to accept that thought. And for them, the lost ones still exist. We may call them crazy, but if you were to ask any one of them they will tell you with all heart and truth that nothing wrong has happened. Such is the power of belief and thoughts.
It is, thus, imperative that we paint the picture of our lives ahead with nothing but the choicest. Really, do you want anything but the best for yourself? I don't. Accept the fact that you have the power to focus on the positive thoughts and take decisions for your life. When you will start taking conscientious decisions- you will start feeling disciplined and feel proud of your existence- and motivated to excel the purpose of your existence. Each one of us is built for greatness-true greatness-how and where it will end is our choice.
My Current State
For the moment I am not thinking where life will lead me, nor am I focusing on the result. I think it will suffice if I just get my thoughts straight (no puns intendedJ) and be as conscientious as I can-and I will get nothing but the best. Because that's what I will give to the world. If you feel it right you can do the same... Never harms to get nothing but the best, does it?
