The thing is to enjoy it. It doesn't matter if you appreciate the nuances or identify all the notes -- or any notes at all. If you enjoy the way you smell with something, that's the important part.

My tastes changed quite a bit over the years, some of which is probably having a more discerning nose, but some of it is just realizing that I can enjoy smelling like all kinds of different things.

In other words: Have fun!
