Our life is always changing every day. The thing that may happen today is different from yesterday, and the choices that we made today have always its relationship with what we choose yesterday. Thus, we can basically say that life is what we make as the saying goes. The little choices that we make greatly affect our lives, thus it is necessary for us to make careful choices every day. In some point in our lives, we unknowingly make choices yet unaware of the fact that it will affect our lives. We do not how whether it positively or negatively affects us, thus making decisions must think well before uttering some words. The vast difference of us make those choices completely without knowing, paying little or no attention to the consequences of each of our actions. Only the very few - what the University of Chicago might term uncommonly successful people - have the presence of mind, the self-awareness, to realize the importance of the moment - every moment - and, in doing so, are all the more likely to choose their actions reflectively, mindfully. The converse, for what the same university might call "normal people" is that we continually build lives that, at best, are "not too bad", by not being mindful of the opportunities that each moment can potentially create. What we feel greatly depends on what we choose to see, and what we decide also depends on the situation that we are to face. We constantly respond to events which is not likely more important, and it is up for use to make bad or good decisions. In doing so, we might feel happy or on the other hand we can be sad. What we decide is what we live to be, thus making life’s choices is always the key to be happy.
