Pondering too much is hazardous

I am currently a 23 years old chap working in an MNC company in India.Joined as a fresher I was doubtful of joining the company or continuing my studies.Although what fate had already decided I ended up in this company TCS.Pondering too much had been a major part of my life, and it led to many late and wrong decisions in my life.When I just completed my high school I was double minded on taking up engineering stream or not. Although life had been quite smooth for me but my overthinking often got me in tough spot.Back then at the time of college admissions I was so confused on taking up which college and which stream that I missed plenty of good colleges although I had good marks.In life sometimes spontaneity is something that is required to move on.Let me tell you how overthinking can be catastrophic. While I was studying in college I tried to chalk out a way to earn some money.The plan was of a small start-up which me and my friends started and was running really good.I and my friends made some very good profit , but suddenly due to one of my friend's decision to opt out of it ,led us to a loss.Now the loss was not that much but again pondering and overthinking took me down the hill.I just focused on how much I lost than how much I gained in the beginning.The loss struck me that bad that I failed in 2 exams and had no interest of studying.One day I was going through some videos in YouTube and got across a wonderful video in which a lady explained a small story of a boy who used to think more and work less and failed everywhere , after that one fine day his teacher made him realize the cause of his failure,from then there was no stopping for the kid.That video was such an eye opener that now I have stopped pondering too much on the results and outcomes and started concentrating more on the action part. Pondering too much clouds your judgement power and slows you down,so keep moving forward , keep your actions as your priority than the results and life will automatically change.
