Fashionable times. Would Jimmy still go to the Rainbow today? Hardly. One goes online. One does not go to the Internet. One simply goes online. At best, Jimmy would go to Rainbow. But probably he would also go online. You surf. You don't write letters or send faxes - you send and receive emails. People don't go shopping - they visit virtual shopping malls, make purchases at the click of a mouse, and pay by entering their credit card numbers. Music plays online. As an entrepreneur, you have the whole world at your fingertips. You belong - as you should - to the new generation that is no longer burdened with the ballast of old economics. Knowing is no longer a matter of knowing, but of doing. Planning, analysis, controlling - elements of yesterday. Today's business follows different rules. The start-ups show the way: one idea, one element.
