Hello George
It is not really frustrating. Try to choose a topic you like so as to enjoy working with it. For example you can choose Basketball since you are expert in it and later you can make review of some items in amazon or any market that are suitable for basketball
Whenever you are stuck, you can ask questions. I know the beginning is difficult but later things will go smoothly
All the best!

It is not frustrating. Go for something you are passionate about, interested in and maybe some of your best hobbies! They all can be your niche

A bunch of good tutorials in the help/search bar. Choosing Your Direction - It Starts With a Niche

Think of basic needs and start from there. You don't need to be an expert. Good luck.
