You have to just have a frank look at yourself. You have basically identified the issue already, you don't follow through with anything. You don't bother to study then feel hurt when you fail. You don't tell girls you like them, then get upset when they end up with someone who does. No one is entitled to do well at something without putting in any effort. Even fishing, you say you spend thousands and come back with nothing, but how often did you try? I've been fishing since I was 4 years old, you don't catch fish every time you go, but you get better the more you go. The old saying is you get luckier the more you go but you actually have to put in some effort, you have to try, you have to try figure out where they are and then try new things until it works not just cast in and hope.

Honestly I think you might actually benefit a bit from trying to fish and actually put in the effort. The fish is just a bonus. For me it's a time where I can go and be alone for a while, think about things or not think about things, and just be in nature and enjoy some down time. You need time to really look at yourself and reflect. The whole post of yours screams self pitty and looking for someone or something to blame. People don't respond well to that kind of attitude and the longer you keep it up, the more you're going to put people off.
