Secondly, I think it is also priority. What's important to you in life? For me, I think it would be my physical and mental health, my family and other things before money. What are your priorities? Is it your top priority to be successful? Or if your priorities are like mine then where are you with that?
Lastly you can try the "vertical arrow"[1] technique which keeps asking the question "What if it was true?". So as an example:
"I will never be successful"
-> "What if it was true?"
-> "I will never have money"
-> "What if it was true?"
-> "I will never be able to impress the ladies"
-> "What if it was true?"
-> "I'll be alone"
-> "What if it was true?"
-> "Everyone will think of me as total loser", etc.
-> "What if it was true?"
Then you write the rational explanation for each with the cognitive distortions in your thoughts. I'm not an expert but do try it maybe it will help you out. It certainly is very powerful stuff to fix your mood instantly.
