Again, this is a faulty assumption. You assume you're not self sabotaging and assuming your steps to goal are the correct ones to increase the odds of success. Etc.
Example.
I want to bag a 15 point buck. So I get dolled up in my hunting gear, grab my rifle, head down to the local lake, and dive in the middle and swim around at the bottom a bit.
When I fail to bag a buck and don't even see any, I then bitch and moan about how everyone who told me I was worthy of a venison steak and deserved the same opportunity to bag my own game as everyone else lied to me. All I got was a catfish. They lied.
Does this make sense?
Example.
I've finally got myself out of the lake and into the forest. I found my buck. He's a 17 pointer. So I pull out my rifle, take aim at my foot and fire. My buddy lied to me. He said I deserved a chance to hunt and was worthy of that trophy kill. Just like everybody else. I don't know why I shot myself in the foot. I panicked at the wrong moment and flubbed the entire sequence of events that has to happen to be successful. That's because I got lied to. Obviously. Just ask Epicurus. Those bronze age blokes know everything, as evidenced by the fact their enlightened status has made their civikizarion and way of thinking and doing things thrive through the ages. Call one of them up and ask them. They're so spot on, they're still around.
Does this make sense?
It's easy to blame failure on people trying to support you and help you through your negative thinking and depression. It's easy to attack them ad liars and swim around in all that comforting negativity till your fingers get pruney.
It's harder to self reflect analytically. It's harder to make changes you need to make. It's harder to be patient. It's harder to do all the things, the adulting things.
