Here's a recent example. I know someone who's very happy she was able to purchase a house in a high-demand area. She'll say "oh, I'm so lucky that I was able to get this house!" But here's the thing, I know she was refreshing market websites all day, and took a tour of the place late at night as soon as it went on the market on a Friday, then put an offer in the next day. Plenty of other people would have noticed the next morning, or said "eh I'll take a visit tomorrow," but by being so proactive, she made her luck.
Determining chances is a matter of WIS, not INT. You gain instincts over time. Until you get that, the easiest way to catch fish is with a wide net, so you'd focus on taking many chances.
To put yourself in better positions, you have to be available and ready to act. I get more fun assignments at work in part because I say yes and get right to it if it's important to the partner who was looking for help. Then, they're more likely to ask me in the future. Most people don't get lucky sitting at home.
A joke I've heard (it mentions god but that's not the point):
A very pious man was devoted to god his whole life. He prayed and prayed, day in and day out. At some point, the man came upon money problems. He asked god "please, lord, I always pray for other people and never for myself, but I need help, please let me win the lottery." It didn't happen. He kept praying every week to win the lottery, but he never won. Eventually, the man started losing faith. He started to curse god, saying "you don't care about me! I've always been loyal and you won't give me this one thing!" Then the lord spoke to him, and hearing god's voice so clearly scared the shit out of him. God said . . . "come on, man, could you at least go buy a ticket?"
I'm sorry you have Asperger's, and I know it does make things hard for you. You know I'm rooting for you to learn to manage it. I believe in you.
