I do not think there is anyone in the world who does not have regrets and have not committed mistakes in life. Best part is, mistakes are best teachers of life.

I do not think there is anyone in the world who does not have regrets and have not committed mistakes in life. Best part is, mistakes are best teachers of life. You are in early 30s, let's say average lifespan of a person is 70 years. So big question is will you let go of your coming 40 years for the lost 30 years? (and i am sure, you have not lost all of your last 30 years, there probably are more positives than negatives if you take a deeper look). Theory 2 - (as said by Peter Norvig) it takes 10 years to be really good at something. Which means you have 4 things that you can be really good at in your coming life. So my friend go claim those.
