You(the blue rectangle) are on the paved road(beige rectangles on the left side). The millions used this road before you, and more will use it after you are gone. You are full of dreams, hopes and energy. You are thinking about going off the road, into the uncharted territory. And what the heck, you could break beyond the red border. But you are smart and experienced enough to not do it on the impulse. The best spontaneity is prepared well beforehand. You are measuring when to do the plunge. You don't want to repeat the fate of those that left only the white splashes after crashing into the fence.
