hmm. I sold my startup because i was offered a wonderful amount of cash. Now my children get a great education. I got to design and build my own house. I get to spend quality time with my well educated family. I have fun, and don't need to work 18 hours a day. I dreamed, created and moved on. Nothing is forever.
