Collecting for the enjoyment of collecting, whatever that might be, is the name of the game. Don't hesitate to ask questions especially if you need basic information and especially more advanced sources of information for any possible topic. You should be able to find folks on this board a little further along on their collecting journey glad to share experiences.
Personal bias. Used stamps are best collected on the cover they carried through the mails. This documents their journey.
Wishing you many enjoyable future days in our hobby. Russ
