Everyone is familiar with how an airplane takes off. It starts by standing still, then it gradually builds speed on the runway and finally when it reaches the right combination of speed it takes off and goes airborne. At that point the pilot can take the plane as high as he wants.
Similarly, when you launch a business, you can take the slow gradual descent of an airplane to reach your heights, or you can take the approach of reaching your heights quickly by making an immediate splash and making money right away like a rocketship.
If you take the gradual approach, it will take more time to reach your heights, and it will take a lot of patience form either investors or working as what Seth Godin calls very lean at the start then build your way to take 3 years to become an overnight success. Some people choose the rocket ship, big splash at the beginning approach. But the problem if you go that direction is that it costs a lot of money and effort even before you begin and if you flop, you'll crash big time.
