Observe and practice before trying to appear cool
I used to take a bus on a daily basis and noticed some people used to get off the bus before it came to a stop. At a round about, the bus would slow down and this would be enough for a couple of people to get off the bus while it was still in motion.
I figured I should try it out once. Big mistake. I jumped off the middle step instead of the bottom so I was going perpendicular to the direction of the bus. The roundabout might have slowed the bus but I didn’t count for the angular momentum. So I landed flat on my back and had a court side view of the truck behind come to a screeching halt. I survived but looking up at the angry driver, I made my way out of there as quickly as I could.
