Bill Gates shared that he feels stupid for not learning any foreign language such as French, Chinese and Arabic.

The billionaire revealed his biggest regret in Reddit's Ask Me Anything. Gates added that he studied Greek and Latin in high school and achieved high grades but he wants to take up classes for the three languages he mentioned. The Microsoft founder wanted to find time to squeeze in French classes, which he thinks is the easiest, according to Live Science.

Gates admitted that he used Duolingo, which is a free site to learn new language but he was unable to continue. The business mogul praised Facebook CEO Mark Zuckerberg who studied Mandarin and held a question and answer event for Chinese students in Beijing, according to CBS Seattle.

Aside from his frustration, Gates also answered light questions such as his favorite cuisine, which turned out to be Indian and Thai. He also enjoys barbeque sauce but makes sure he does take it before he appears on a TV show since he usually spills it.

Just like an ordinary career person, Gates also treats himself. The billionaire revealed his "biggest splurge," which is a private jet. Since the Super Bowl is coming, Gates said that he will be supporting Seattle Seahawks since he lives in the area and is "good friends" with the team owner Paul Allen.

Clothes and Food are not Gate's priority when it comes to spending a good amount of money. The businessman prefers to purchase racquets and shoes since he loves to play tennis.

Fans also wanted to know what life lesson Gates can offer. The philanthropist instantly shared his struggles with sleeping early. Gates advised that people should go to bed early "even if the book is exciting" and added that staying up late is something people will regret when they wake up.

Gates currently lives in a $120 million mansion in Medina, Washington. He lives with his  wife Melinda, three kids and two dogs.
