So I bought my 1st car, a blue streak metallic corolla LE! It's so shiny

I heard that I need to keep waxing the car to maintain the glossy blue paint. Is it true? If so, NOW I'm totally lost! First off, when do I have to wax my BSM car, yearly? monthly? Should I do the wax myself? or have a professional do the waxing? If myself, what should I use as the wax (I hope its not too expensive!) or how much would a professional do it? I'm just curious, What would the car look like if it was never waxed?
I'm sorry the post is doubled.
