He was no scholar, and his classmates teased him.Rather than reading, the kid really preferred running around with an 8mm camera, shooting homemade movies of wrecks of his Lionel train set(which he showed to friends for a small fee)

In his second year of high school he dropped out.But when his parents persuaded him to return, he was mistakenly placed in a learning-disabled class, he lasted one month.Only when his family moved to another town did he land in a more suitable high school where he graduated eventually.

After being denied entrance into a traditional filmmaking school, Steven Spielberg enrolled  in English at California State University at Long Beach .Then in 1965 he recalls ,in one of those casual moments, his life took a complete turn.Visiting Universal Studios ,  he met Chuck Silvers, an executive in the editorial department.Silvers liked the kid who made 8mm films and invited him back sometime to visit.

He appeared the next day.Without a job or a security clearance ,   Spielberg(dressed in a dark suit and tie, carrying his father’s briefcase with nothing inside but “a sandwich and candy bars’’)walked confidently up to the guard at the gate of Universal Studios and gave him a casual wave.The guard waved back.He was in.

“For the entire summer,” Spielberg remembers,” I dressed in my suit and hung out with the directors and writes including Silvers, who knew the kid was not a studio employee, but winked at the deception) I even found an office that was not being used ,and became a squatter.I bought some plastic tiles and put my name in the building directory: Steven  Spielberg, Room 23C〞
