och..
learn how to stop as fast as possible... never assume that anybody see's you.. imagine you are invisible at all time..
be prepared to swerve, accelrate, stop, or die (you can pick which one when it happens during the .2 you have to decide which is the best course of action) at any given moment.. especially in traffic..
wear as much gear as you can pack onto your being.. i mean suit of armor if you can get one.. carbon fiber underwear with a cup, 2 helmets.. one extra small.. one xxxxxl to fit over the one if possible.. Man just get all the safety stuff you can and use it everytime you ride.. I"m not just saying that cuz your new.. everybody should do that. At the very least full leathers, high quality helmet (i didn't say high cost I said high quality.. DOT/Snell rated at least) good riding boots, and gloves.. again.. don't buy the cheapie "no real protection" model.. splurge a bit.. it's your bones/skin afterall.
don't ride like a maniac... especially in cities.. you got some unpopulated roads/places.. go there to play.. nothing will put your ass on the pavement faster than actin' the fool on busy streets.
other than that... you shouldn't ride.. it's dangerous to your health.. and you will crash at some point.. everybody does. I know guys that have never had a real wreck in 30 years that had to be med-flighted and they still can't remember what caused the wreck.
ride safe, use your head, going fast is great.. as long as you do it as safely as possible.
