Elon Musk talks of his life's 'highs' and 'lows' in a few painfully honest tweets

Think it's easy being Elon Musk? Think again.

As the CEO of automaker Tesla and private space transport company SpaceX, founder of neurotechnology company Neuralink and tunneling company Boring Company, and a key figure in AI non-profit OpenAI, Musk is obviously extremely busy. He's also a billionaire and gets to play with ultra-cool high-tech toys, which sounds like a geek's dream come true.

But in reality, the good times are mixed with the bad, and the way Musk just described his life on Twitter, we're not sure many would trade places with him.

Answering a Twitter user's question about his "amazing life," Musk said it consists of "great highs, terrible lows and unrelenting stress."

Ouch. Musk even gave a recipe for dealing with all that stress, although by his own admission it's probably not the best answer: "take the pain and make sure you really care about what you're doing."

In another tweet, Musk took it even further. He was asked whether he was bipolar, and he flat out said "yeah."

But in the next tweet, he said his condition might not medically be considered to be bipolar disorder.

Finally, Musk summed up by implying that taking on so many stress-inducing responsibilities is his own fault.

The painfully honest tweets come days after the official launch of Tesla's most affordable car -- and likely the most important one -- the Model 3.

During the launch event, Musk spoke about potential manufacturing problems, saying that the next six months will likely be "hell."

This is not the first time Musk has opened up about the problems that come with running so many high-profile endeavors at once.

During Tesla's annual shareholder meeting in June, he talked about his insane schedule and the steps he's taking to alleviate some of that dreadful stress, including drinking less coffee, sleeping more and allocating some time for dating.
