Your path is individual to you. Learning online or off, you will want to take in as much information as you can from respected sources. Research and practice. Study the basics and dont be in a rush to cast a spell. There are some wiccans who do not cast spells at all. Its easy to not know what you want when you do not know what you have to choose from.
There are a lot of ways to get started. When I first begin my journey, I read up on the history of pagan religions, The different paths and beliefs. Once I figured out what path felt right, I worked on meditation and opening my minds to the divines. Then I learned how to focus my energy and control it. Most people like to just jump into spells without understanding it. I'm still learning myself, but I'll be glad to help in anyway I can. If you have any questions, feel free to ask. I remember how hard it was for me to get started.
