The Good Luck

Good and bad luck are very powerful beliefs that are deeply rooted within the modern culture, as a result of multiple practical, religious and superstitious ideas, that have evolved throughout history. However, is good luck a matter of superstitions, random circumstances or attitudes and skills? Is there good luck?Considering that the superstitious thought is proper of the human being, it can be debated whether good luck is a matter exclusively of superstitions, random circumstances or personal attitudes and skills, or if it depends on all these factors (being some more important than others, or if almost all of these are mainly influenced by random circumstances).
Likewise, it is obvious that this position of the majority of scientists, academics and researchers (backed by Judeo-Christian beliefs) is correct: there is no luck. Therefore, it is everyone's responsibility to be aware that good and bad luck are inventions of the human mind (which try to justify inexplicable and uncontrollable events), make the best decisions, and act correctly, in order to have a satisfactory life, achieving various personal and professional goals.
