I have just started looking at all of this today. I have read the basics and know how to cast a spell. I just feel like I'm drowning in all the information. Is there anything I should know before casting any spells other than how to? Is there a spell I should do before any others? Is it safe to practice spells? I have no intention of hurting me or anyone else. I really would like to protect my friends and family as much as possible, so is this a good idea?
