"ペイパルの買収による収益は1億8000万ドルでした。1億ドルをスペースXに7千万ドルをテスラに1千万ドルをソーラーシティに投資しました。家賃のためにお金を借りなければなりませんでした。"

Simplified Meaning:

Imagine you had a big sum of money from selling your business. Instead of keeping it all for yourself or spending it on luxuries, you decide to invest almost everything into new projects you believe in. This is what happened to Elon Musk with the money he got from selling PayPal. He put most of his money into three new companies: SpaceX, Tesla, and Solar City, which all focus on changing the future in big ways like space travel, electric cars, and clean energy. Because he invested so much, he didn’t leave much for himself and had to borrow money just to pay his rent. His story shows deep commitment and belief in his ideas. If you believe strongly in something and are willing to take risks for it, like he did, you might face some tough times in the short term. But these sacrifices can lead to big rewards in the future. It’s about putting your money where your mouth is and going all-in on what you believe will make a difference.
