Here are some quick thoughts on how you could improve the essay:
Change all instances of "the" to "its" in the first sentence.
Revise "I am a person who is a researcher, scrutinizer and prolific." The phrase "a person" is unnecessary, and the list violates rules of parallel structure. Consider "I am a prolific researcher" instead.
"figured" sounds a bit informal. Replace with "believe" or some such.
"These skills will make solving problems easier and force me to use my brain in my life." Again, a bit informal. Try "These skills will make solving problems easier and help me become a more thoughtful individual."
"Through search, I realized that Industrial Engineering is the ideal field for me." Consider "After a long time spent reviewing my options, I realized that Industrial Engineering was my ideal field."
"It involves both manufacturing and supervising and also a prevalent and promising major" The second part of this sentence needs rewriting. Or possibly simply deleting.
