Experience that comes from bad judgement

I bought a cute little Honda scooter. It's brand new and I am riding it to and from work and around a few local destinations. I am also learning to drive a forklift type machine at work called a narrow-aisle high picker. Powered Industrial Equipment (PIE) which uses a hand control somewhat similar to the throttle on my scooter. Unlike my scooter, the PIE goes in reverse when you roll the handle down while my scooter goes forward when the handle is rolled down. This presented a problem for me the other day when I had been using the PIE all morning to pick parts. I got on my scooter after getting some lunch there and went to back up only my scooter shot forward, hit the curb and we both went down with a crash. Neither of us is quite the same. The scooter has a few scratches and I have some bumps and bruises. I had completed my motorcycle class last weekend and had to drive a motorcycle with a clutch and gears and a foot brake. My scooter is always in gear and only has the throttle and brakes. So I learned the hard way what my instructor said, "Good judgement comes from experience. Experience comes from learning from bad judgement" I learned that my scooter doesn't have reverse and if I want to go backwards I will from now on be sure the engine is off!
