Quote by Antonie van Leeuwenhoek

"I have always endeavored to use my eyes as accurately as possible."

"The more one observes, the more one sees."

"Nature is the greatest teacher if we are patient enough to listen."

"I do not pretend to know more than I can see with my own eyes."

"I believe in working hard for what you want."

"Never underestimate the power of determination."

"I don't need a reason to fight."

"The most important thing is the mission. Nothing else matters."
