Greetings and welcome!
There's so much info here that learning can be like trying to take a drink from a fire hose. Take your time and enjoy reading some lifestyle forums (full timers, solo), hobbyist (cooking, photography, lots of things) forums, and the technical things, too.
Good luck and have fun as you begin this adventure.
