"Small tasks" - Common App work experience essay

please help me edit the essay

"Small tasks as moving boxes or packing documents are as important as other works that are being done in this building" It was the first comment manager made when I've received an internship at Mirae Asset. I could not understand his comment at the time, but after spending first hour at the company, I realized that I will be moving heavy boxes and packing insurance documents. I was little disappointed that I was ordered to do such meaningless tasks because I expected something more complex such as organizing files or working on computer. Although I was going to do whatever manager ordered me to do, I wished to obtain experience in Insurance. It was manager's comment "In order to be an important person who does important tasks, you have to do smaller tasks" that motivated me to work passionately. Now, I understand seemingly trivial tasks are necessary for the success.

You might want to explain just how moving boxes and other "trivial" tasks are important. At the moment, you just say that that is what you were told. If you truly understand it, you should be able to explain it, though.
