"Knowledge is a real power," a quote proclaimed by Anna-Maria Petricic. Knowledge is the most valuable possession that can never be stolen by anybody. It is instilled in the mind and will even nourish as days pass by. Knowledge can come from schooling and usually from everyday experiences. During these circumstances, there are a lot of people behind it that contributed a lot with our knowledge.

As the time went by, I gained more knowledge. I have been through different situations in life that molded the knowledge that I have right now. There are a lot of people who influenced me. Different people have come in and out of my life. Some did not last very long and some still remains as part of my life. I value each of them whether they do me good or even just brought harm to me. They are part of my experiences that helped me craft the knowledge that I have. My family, teachers, peers and even my enemies were the people who contributed to craft the knowledge that I now have.

Good evening :)

"...and some still remain a part of my life. I value each of them whether they do me good or have just brought harm to me. They are part of my experiences that have helped me craft the knowledge that I have. My family, teachers, peers, and even my enemies were the people who contributed to crafting the knowledge that I now have."

You use the phrase "craft/crafting the knowledge" that you have many times; this is redundant, so try mixing up your word choice a bit so that you readers don't get bored.

I hope this helps!
