I really wanted to share this with you since my mother always tells me, and her words are wise and are full of reason. It is better to learn from the mistakes of others than to commit them too. It is true that we can learn from our own mistakes but it is better to avoid the blow.
Many people say that it is better to learn from our own experiences but I do not think that it should always be this way, what I mean is that it is not necessary to hit the same stone that the other has just carried away. Just by looking around you I can assure you that you can realize the things that are not right and that you do not want to happen to you.
For example, when I was in high school, I saw how some of my classmates did not enter class and did not take their studies seriously. Then when the period ended and it was time to deliver the grades, for obvious reasons their grades were low. When I saw them, I realized that what they were doing was wrong and I knew that it was not what I wanted for myself.
However, many times we do not take this into account and because of our stubbornness we want to find out on our own, knowing already what can happen to us. The important thing about all this is to learn and keep in mind that there are other alternatives, you do not have to go on and on crashing against the same wall.
All this helps us a lot, both our own mistakes and those of other people; we learn from them and it helps us grow as a person.
