Often we wonder,

1) What are the things in my life which I should have done better?
2) Skills which should be concentrating for my next promotion at work place?
3) Better decision making/managing our Personal Finances?
4) What should be considered as Short term goals? Long term goals?
5) Do I have both Short term/Long Term goals defined which I should be focusing on? Does the goals align with my priorities and values?

It's true that there is no gain in mulling over the things that went wrong in our life. We can't correct the past, but we should be looking forward and think how can we make sure to set it right next time. I call it "Internal Feedback system" - a key system for correcting our mistakes and improving our productivity and life style.

I came across the below blog today, related to the above topic which I thought of sharing.
