First, never listen to a person with YOLO in their name from NJ. Seriously, if you learn nothing else, learn this.
I LOVE to Uber. That doesn't mean it's not work or that the money is good, that depends on you and your area.
I would say, from what I've read here, TALL and coastal cities suck. WIDE and non-coastal cities are way better. Longer runs and more polite passengers.
Don't be scared at all, it really is fun if you are patient and outgoing, but do be prepared. You can have 15 great rides killed by one bad one. The trick is to remember YOU are the boss and don't let the bad one happen.
Lock your doors and talk to pax through a window. They have to know your name, period.
DON'T start the ride in the app until you are sure YOU want to give them the ride. If you don't like the ride for any reason, drive off and then cancel in the app, really, do it, you decide not Uber or the pax. Do this on an iPhone by tapping their name, select cancel, and select whatever reason you choose.
If you give the ride, be nice, be mostly honest that you are new, and turn on your GPS voice if you are new to the area. Do that by tapping the audio icon in the upper right corner. It's off by default.
In the tall cities, amenities might be worthless, here in the midwest I rake in the tips with them, do what you want and see if you think they work. You don't need them to do your job.
If this isn't for you, you will know it soon enough, but don't be scared to try. 95% of my passengers are rich people, tourists, or college kids. Not scary. The other 5% are people I drive away from and cancel like falling down drunks or people who try to break the rules.
