I do believe in luck. I think that there are some things that happen because they are meant to happen that way. There are some people who are considered luckier than others so even if they are not as good as other people, there are opportunities that are coming their way.
Those who are lucky may have more means to do what they want as compared to those who cannot be considered lucky. Luck can change things too. For example, even if someone who is expected to not do so well might actually become lucky for that certain day alone. The person will achieve more than what is expected.
