How did Albert Einstein overcome these syndromes to become a world renounced scientist?

Albert Einstein was an autistic-savant, meaning he was very knowledgeable in certain fields of interest, but was completely incapable of learning things outside of his interest-fields. Einstein had a lot of trouble interacting socially, and relating to other people. He was completely uncommunicative until the age of 3, and then started speaking in an echoing pattern called "echolalia." Savants are autistic people who have certain areas of expertise. The ones who aren't savants are considered "profoundly autistic" and have more pronounced cognitive impairments. About 25% of autistics never develop speech.
