So I Got a Fancy New Camera.. Now What??

I've been going back and forth for months now on buying a professional camera to take pictures of my work and start a new hobby. I watched so many videos and read so many articles trying to decide. I even picked the associates' brains at stores trying to get their opinions as well. After months and months I was finally in a position to buy one, and now I'm kind of scared to start snapping shots. I now understand why people are afraid to try something new.. we don't want to be bad at it. I've read half of the users manual and I'm still not very confident and almost feeling follows about my purchase. I have to remember everyone has to start from somewhere, and we'll never get any better if we never even try. Wish me luck beauties!!
