Well that's what happens when everything you try comes crashing down because of some reason or another.
I strongly doubt this. In fact, I would bet that it's next to impossible to fail at everything
. And even if you did fail at everything (which is an absurd notion, since you simply wouldn't exist to even try), it would still not be evidence of the universe conspiring against you.
Not only that but you are not the most reliable narrator of the events, as your perceptions are so heavily skewed toward pessimism and defeatist interpretations. Saying you put "a lot of effort" into something is devoid of any information by which any of us here can realistically assess the risk of failure, adequacy of your efforts, and whether or not you stood any chance of success. It is for this reason that I remain skeptical of your efforts. Please understand that I am not saying that you are exaggerating or that you don't experience distress because of your experiences. What I am saying is that your account of the events is heavily biased and unreliable and because of that it is impossible to comment on the soundness of your observations/interpretations, specifically whether or not any of your failures were avoidable and what, if anything, can be done to improve your chances of success in the future.
To go back to the main subject of your thread. I do not believe in luck as some sort of outside force that arbitrarily affects people's fortunes, to me that's just nonsense. The way I see things - a person has to first register an event, establish a relationship between said event and their life or immediate circumstances (or the life or circumstances of another person observed), this event has to have some discernable impact on the person, which then can be subjectively judged to be either favourable or unfavourable to the person in question. Luck is just a sense of agency that some people bestow upon the most notable of the consequences of such events and their subjective value.
To illustrate how unreliable, and context dependent our subjective interpretations of the events are, here's an old Taoist story:
A man named Sei Weng owned a beautiful mare, which was praised far and wide. One day this beautiful horse disappeared. The people of his village offered sympathy to Sei Weng on his great misfortune. Sei Weng said simply, “That’s the way it is.”
A few days later the lost mare returned, followed by a beautiful wild stallion. The village congratulated Sei Weng on his good fortune. He said, “That’s the way it is.”
Some time later, Sei Weng’s only son, while riding the stallion, fell off and broke his leg. The village people once again expressed their sympathy at Sei Weng’s misfortune. Sei Weng again said, “That’s the way it is.”
Soon thereafter, war broke out and all the young men of the village, except Sei Weng’s lame son, were drafted and were killed in battle. The village people were amazed at Sei Weng’s good luck. His son was the only young man left alive in the village. But Sei Weng kept his same attitude: despite all the turmoil, gains and losses, he gave the same reply, “That’s the way it is.”
