Imagine you could go back in time when you were 10 years old but retained all your current memories. How differently would you live your life with that knowledge?

Given that I currently work as a full stack web developer I would not have done my Masters in Mathematics. I would have chose Computer Science. And I would have only given 1 or 2 attempts for UPSC. I really would have missed the amazing time that I had during my Masters and I would have totally missed my friends from college but this academic thing is the only thing I would have changed with regards to my life.

My current professional life would have been simpler. I would not have wasted my precious youth in UPSC preparation so I would have lived a little more happening life during those years of prep.

Everything else in my personal life I really wouldn't change. I just would have understood why people were behaving the way they were behaving and changed my expectations accordingly.

What would you do differently?
