Maybe we could have taken another route that could have taken us to where we wanted to go and that is why we should not regret it, nothing in this life is in vain, something we learn, then, is to move forward, I remember so many times how things did not work out as I had planned and this never stopped me, on the contrary, it gave me more strength to move forward and in the new course set.
It is not strange that if we start counting the times we fail we can find that this amount exceeds the times we have succeeded, and this happens to all the people we know or who inhabit this planet, the regrets are in their cases defeated and frustrated by not continuing do not become one of them.
When we fail for things of importance to us we should concentrate even more, and when we regret not continuing in our struggle to achieve success, that is the mode of regret that should be in our mind otherwise we should not regret the failed attempts to improve ourselves.
Nobody at best carries the relationship between triumph and defeat unless they are statistical numbers of a baseball pitcher, I do not do it but what I do is to enjoy every achievement and learn from the failed attempts, nobody is perfect in this life and therefore we can not regret trying to have good and better things for our life, as long as we do not damage the integrity of any person we should not use the word regret in our mind.
