I meant, what is an exactly certain situation anyway? Is there such a thing?
Personally, I know that it is not possible to escape uncertainty. It is the degree of uncertainty that varies. In some situations you may found it fairly uncertain while in some others severely uncertain.
I grew up in a highly religious society. Like many of such societies, God is the ultimate power by whom decision or outcome of anyone's life is decided. Therefore people believe that they do not have total control of their life, therefore their outcome. As there is always an "invisible" hand interfering with every body's life. Thus, gives rise to the notion that life is uncertain.
Do you believe that?
I believe that life is uncertain, not because I think God has a 100% intervention upon it. Not that I disbelieve the existence of the ultimate higher being. Although, I neither testify his/her/its very existence. I think life is uncertain simply because it has so many factors that may factor in an outcome of an event. Take for example, the occurrence of raining. There are a lot of things that determines the event of raining. Not only either it will or will not happen, also these things determine the intensity of the event, namely heavy or light. The amount of water vapor in the cloud, the temperature, the amount of water in the land, the level of pollution, or many other factors. Therefore, It is impossible to tell how it is going to be rain exactly.
Nevertheless, with the advancement of science, we are able to at least predict with a fair chance of being correct the possibility that it may rain. We know that if the amount of water vapor in the cloud reach a certain level, most likely it will rain. Or maybe other measurable quantities leading to the occurrence of the event.
Applying this analogy to our life, to our future, it is impossible to picture and exactly getting what we want. However, if we are doing the right things and making sure that we are doing them right, the predictability of the expected outcome can somehow be foreseen, just like how we forecast if tomorrow is going to rain.
