not really struggling with any thing at this point. Just starting out to be honest. Haven't made any gear purchases. I mainly just hike with a old backpack I had from college. I was just looking for any advice on useful gear, or things to avoid, etc.
Pretty much everything neni said. Your biggest enemy with backpacking is weight. Leave anything you don't absolutely need behind. Even 1lb of extra weight will make a big difference when hiking in 6+ miles.
