Does motivation help people to succeed?

I think yes. I am the living example. Motivation really helps people to achieve goals. Because motivation is a pulling circle that people make themselves. When I was studying at school in 4^th grade I was too careless about my marks. But when my teacher gave me a certificate about finishing the 4^th grade with excellent marks I realized that if I start studying I can get another certificate. So, I made it. The certificate which was given by my teacher was a pulling circle that helped me to be one the excellent pupils of our school. I understood that if you are not educated nobody respects you and you cannot understand the meaning of life.
