Drive it like you stole it. You’re gonna do poorly for a long time until you get your head wrapped around it, so just be curious and see if that thing DOES kill you. Then you know to avoid it. There are some good tutorials on YT that can help. Might be a bit dated, but should get you a decent start. Good luck!
