I was around the same age when I joined!
Being a satanist at such a young age saves you from doing a ton of mistakes that average people do in their lives such as starting bad habits like drugs ,alcohol,smoking, or getting close to fucked up people. Practicing magic and meditation while still a teen gives you a ton of opportunities. You can eliminate a lot of your negative karma that can potentially give you a hard time later in the future. Magical workings and specific meditations can help you improve your efficienty at school ,making it easier to attain higher education and job afterwards. They can also help you attract some worthwhile people to have as friends so you can have a good time without associating with wrong people!
Keep advancing and enjoy this spiritual journey.
I give you my best wishes!
