Have you ever had a experience where reflecting on your action benefited you

Yes.

Explanation:

I believe that we have all had experiences where our reflection and interpretations of our own actions have benefited us, which shows that we must always reflect and think a lot about what we are going to do, before acting on impulse and in a totally inconsequential way.

In my case, my reflections on my actions prevented me from changing college courses, when I thought the course I was taking was not cool and I thought that there were more important courses for society. I wanted to exchange the course in Agricultural Management, for Chemistry. However, after thinking about it I realized that I did well in the course I was taking and that I didn't have an affinity with chemistry. In addition, I realized that my course was very important for society and that I should do my best in it. This was very beneficial for my life, for my future and for my academic growth, so that until today I do not regret not having changed.

explanation: we can only guess at how our actions may be perceived in the future. doing something really big like killing lots of people, saving lots of people, affecting the lives of lots of people is a sure fire way of being remembered in historical records. we can also make a difference in the history records by being a small influence on something bigger, whether that is as a civil servant, scientist or artist.

of course you could argue that we all affect history just as tiny cogs in a   bigger machine.

if you mean how do people influence our opinions of things which have already happened, then simply by writing a book which looks at things form a different perspective and trying to convince people that this perspective is more accurate or truthful. people do it all the time i.e. richard the third was a terrible or was he? plenty would disagree, it's just that their views aren't the most widely known.n:
