The Feeling that I'll ALWAYS make the wrong decision

Whenever I was about six, or seven, I was in the Primary School Playground; with a plastic bag on my head. I wanted to be a Knight. However, the supervisor said, to me, "You'll suffocate doing that!"

Ever since then, I always felt that the decisions I make will ALWAYS be wrong. Reinforced by;

1. My Favourite Sports Teams not getting the cash-and-prizes than rivals.

2. The Subject decisions I made not leading to a successful career.

3. My Political leanings associated with corruption, and World-Domination.

4. My Favourite TV Shows being shelved, due to Headline News.

This whole self-defeatism isn't helped, by my autistic brain.

Anyone else have similar feelings?
