Because the beach gets boring after a while. At my last company our lead investor was Rich Janssen (great name, right) and he said exactly this. He founded Realtor.com and took it public and founded a data analytics company that sold to Myspace. He had a $10M house in Montecito, CA next door to Oprah, and a million dollar yacht. I asked him why he didn't just retire to some warm sandy beach. He said he tried retirement but it didn't work. Golfing and sitting on a beach made him feel old. Working with young people made him feel young.
