I'm 52 and until January of this year hadn't flown much beyond a paper airplane. I bought my Mavic direct from DJI, and while it was in transit I took the time to download the manual to read and watched hours of YouTube video tutorials on flying and camera settings. DJI has their own YouTube channel with some very informative videos on The Mavic (
DJI Tutorials). When it finally arrived, I fired it up (without flying it) and set all of the settings that I'd learned about through reading and videos. I waited another day or two, because like you I was nervous, then took it out to a soccer field by my house to fly for the first time. No trees, and flat as a pancake. I flew in beginner mode the first two or three outings, then took off the training wheels and went to a nearby park where I took it out of beginner mode for the first time. I fly at least once a week, and am in forums like this and YouTubing daily learning new techniques and camera settings. About six weeks ago, I took it to the ocean and flew out over water for the first time. My knees were literally shaking, but I kept reminding myself "This is what you bought it for". Tripod mode has a top speed of 4 mph and is really cool for flying tight spaces, but I prefer cinematic mode which also slows down the drone but not to that extreme. Tripod mode is not practical for every day flying. DON'T fly indoors unless/until you're very confident. Your drone will most likely not have a GPS signal and be in ATTI mode indoors. I've seen at least a dozen videos of first timers firing up in their living room and flying into a chandelier or wall destroying their new drone and in one case a guy's brand new 4K TV. DO NOT PANIC when flying. If you feel that blood rushing to your head, simply let off the sticks and The Mavic will hover in place while you collect your thoughts. This thing is super intuitive, and 99% of the problems that I read about are due to pilot error though it's much more convenient to blame it on DJI than eat crow. I'm a little overly cautious, but I typically won't fly mine below 17% battery life. That depends, though, on how far out I'm flying. Definitely over water with an ocean breeze I'm reserving at least 20% battery to assure that I have enough power to get back safely. I am also a homebrewer, and as Charlie Papazian a renowned brewing author says, "Relax. Don't worry. Have a homebrew". Here's the link to my ocean flight. Yes I was nervous the entire time, but seeing the reward in the end made it all worth it.
