If we can learn from our past experiences, we will surely be better persons... But, saying is easier than doing self improvements, as desired... Preaching is always easier.. Doing needs a lot more.. Life is action. Life can't be a series of lectures and preaching activities... One self advice implementation is million times more powerful than lectures by self or others.. We should follow Just Do It. Forget everything else, except doing your own works as perfectly as possible possible. Giving our best efforts is all in life... Being selfless is at the root of all happiness and satisfaction...
