Microsoft founder Bill Gates has revealed what makes him feel like a fool. The global philanthropist was asked on Reedit, a social network chat “Ask Me Anything”,Wednesday, if there was anything in his life that he regretted? ”I feel pretty stupid that I don’t know any foreign languages, I took Latin and Greek in high school and got A’s and I guess it helped my vocabulary but I wish I knew French or Arabic or Chinese. I keep hoping to get time to study one of these – probably French because it is the easiest,” the 59-year-old told Skynews. While paying glowing tributes to Mark Zuckerberg, founder of Facebook founder said he was delighted with the Chinese audience last year with his Mandarin skills. Mr Gates continued: “I did Duolingo for a while but didn’t keep it up. Mark Zuckerberg amazingly learned Mandarin and did a Q&A with Chinese students – incredible.” The former Microsoft chief, who is the world’s richest man with a net worth of more than $80bn (£53bn), can certainly afford the language lessons.
