During a recent lunch meeting, Ashwin Rangan, CIO of Walmart.com talked about this concept. So, credit goes to Ashwin.

One of the key things in life is to “selectively forget”
things. There are so many things that happen to us during the course of
our lifetime. I always say “either we win or we learn” When we “learn”
life is giving us some feedback. The feedback and learning is what is
important. There is no point in recreating the entire scenarios once
the learning has happened. I talked about it in some sense when I said “Use your thinking bandwidth wisely.”

Wouldn’t it be nice if you review your day and mentally capture the
learnings from the day and decide to “selectively forget” certain
things. I am sure there will be less clutter in the mind to deal with.

Thanks Ashwin.
