Life is filled with luck, both good and bad. Two workers can have the same training and education, and go to the same job interview. If one got spoiled food for dinner at a hamburger place the night before, and spends the job interview running to the bathroom the other will be more lucky in getting the job. Two dogs may be the same breed, and live on the same block. Yet the one who runs after birds in traffic when his owner left the gate open will have less good luck. Hard work plays a role, but so does raw fate no matter who you are or what is your work. At some point you just have to let go and know you can’t control the universe.
