Just like any other hobby, the amount of self education about what's available, how it works and what it costs is essential with the added caveat here of what does it sound like?
If you have friends close by with good systems you can learn more much faster as you hear them. Systems in retail stores and at audio shows aren't usually an accurate guide to what that same gear will sound like at your house in your room but can give you a rough idea of price and direction.
Trust your ears. Read equipment reviews but realize they usually aren't as objective as you might think they are.
Finally, enjoy the journey. Music is the best.
