Musk spoke at the G20 summit: I work seven days a week, and I don't recommend it.

Beijing, Nov. 14 (Xinhua) Elon Musk, the world's richest man, said at the G20 Business Summit in Indonesia online on Monday that he still has to run Twitter after buying Twitter for $44 billion and has too much work to deal with.

Musk attended the business summit on Monday, wearing a traditional batik shirt from the Indonesian island of Sulawesi. "my workload has increased a lot recently," Musk said. "there is no doubt that I have too much work to do."

In addition to Twitter, Musk needs to run electric car company Tesla and rocket company SpaceX. In recent months, some Tesla fans have worried that Musk's attention to Twitter may distract him.

Asked how to manage Tesla's increasingly global business, Mr Musk replied, "I have to say, it's very difficult". "I really work seven days a week, busy from morning to night, working as hard as I can," he said at the summit. "frankly, I don't recommend it."

He also said Twitter needs to post more videos, including longer videos, and should pay for the creators' work. These are two ideas he mentioned in his previous acquisition of Twitter.

In addition, he reiterated that Tesla was considering producing a cheaper car, but did not provide further details. "We do think it makes a lot of sense to make a much cheaper car." He said. More than two years ago, he first suggested that Tesla might launch such a car.
