If i have never done magick before and i have no magical background in my family, can i still be able to cast spells and do magick?

Sure. You don’t need to have a background in magick to practice it. There are lots of good books on the subject to get you started. 90 percent of magick is intent, so if you believe that you can do it, you can. I usually recommend anything by Scott Cunningham to get started. You can find his books both new and used at your local used book store or on amazon.com.
