Any Regrets ??

I have always thought of myself as a  progressive person. A person who does not look back and think if something could have been done differently....People always say that never look back and do not regret anything in life, what is done is done.. I wonder how they can think like that.. 

A few days ago I started thinking of this No Regret policy :) 

I think it does not work , come on who are you kidding ?? There will always be something or a lot of  things which you will always regret and want to change ..... 

Most of these things will always be something to do with the people whom you have known ..... some who have treated you badly or some whom you have treated badly... There is always something which you could have changed, and something you would not have said or done ... 

Some crucial life changing decision which you would not have taken if you had the chance to wait it out ..... 

What a complex piece of time and space balance we live in .... sometimes i feel like running to a mad mad scientist and asking him about the time machine he promised to the world so that I can avoid the mistakes and the hurt .... 

Any takers ?? ..................
