When I first started practicing paganism there are several things I wish I knew. I spent a lot of time reading and surfing the internet for information. Some helpful and some completely out there sources exist. Here is a list of somethings I really wish I knew in the beginning. In no particular order of course.
1.) There is no right way. Paganism is all about what you make it. If you believe in the Wiccan Rede, go for it! If you think you should eat meat, do it! This religion is about respect, including everyone's ideas, it doesn't matter if you agree or not.
2) You don't need a coven. Just because you practice alone, it does not mean you are not pagan. Covens are great fun, but they are not always for everyone. Covens rely on everyone following the same rules and those don't always line up with what you believe, and that's okay.
3)Stuff is nice, but not required. You will find lists, upon lists, upon lists, of things you "need". You don't. Not really. No one needs 300 dollar ritual robes, the crystal candle holders are fabulous but the quarters don't care what they look like, and the broad sword you bought for 1000 dollars gets really heavy. When you practice it is about your relationship with the deities not how much money you spent on stuff.
4) Casting isn't everything. You can cast, but it doesn't make the religion. Paganism is about worshiping the earth. If you choose to connect with the earth and make requests of it that's on your terms. It does not make you a bad pagan if you don't do it either.
5) Meditation takes work. I have fallen asleep so many times while practicing meditation it may almost be insane. Some people get it right away, others fall asleep every other time.
