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."

"Success comes to those who never give up."

"Success is measured by happiness, not money."

"You make your own luck in this world."

"You have to be organized to be successful in anything."
