Some dreams never do come true.
Maybe you've always wanted to jump out of an airplane, but you promised your wife that you wouldn't do it as long as she was alive. Maybe you should have gone to law school after all, but now you are fifty-five, nearing retirement, and not about to embark on such a huge commitment of time and money. We all die with unfulfilled dreams, that's the nature of life. Some dreams are better off in your head as a fantasy than something you actually pursue, especially if you are married and responsible for children. If every corporate executive or blue collar worker quit their jobs to pursue a dream, we'd all be in a lot of trouble, and so would their families.
