Each day, we grow and learn from the things around us and of course the various transaction we find ourselves in. Whether it is for work or from socialization, you can be assured that lessons and points picked up from them add to your personal judgment in the long run.
This is not to say that new ideas and facts can alter what your personal philosophy is about. In fact it would depend on your stored knowledge. For some, it may not matter but for others, improving or perhaps correcting initial understandings is apparent. But not all gathered new information can turn out to be for the good. In fact, it can push right judgment into false ones, depending on how well a person is able to weigh things out between them.
So in the end, something gone wrong or right will entirely depend on how a person is able to depict situations. It can mold them into better philosophers or perhaps into controversial ones. Once that happens, the evolution of sound judgment cannot be easily altered. You just have to be aware that changes in personal aspects can be noticed one applied.
In the end, a person will have his own philosophy which may not necessarily be common to others. There is nothing abnormal about that. The only thing that remains is to live up to that philosophy and see if you can improve it for the better. If there is something wrong it can be easily seen. Depending on pride, a person can change for the better if he does choose to do so.
