I have a big Over thinking problem and it is ruining my life to the point that I can't get anything done. Even small tasks take hours. I have exams in 2 months and I'm always thinking about the perfect plan for studying but I've not studied due to that. I have many books for different skills, many ideas that I want to execute and many projects that I want to do but I can't get shit done. All I do is obsess over it and let the time pass. How do I think straight without complicating the process? How do I stop my obsession with tiny details and upcoming failures that I keep thinking of? Any advice will be helpful.
