well, if you know how to charge, focus and ground, you're ready. without that, your spell won't work. i'd work on that first. while meditating, feel energy entering your body, then feel it leaving your body. the most common way is visualize white light entering your body then think of roots going down to the ground. there are many other methods, but that's the one i was taught.
from their, i say candle magic is easiest. you get a candle of the colour your spell requires [yellow=friendship, white=protection] you light the candle and watch it burn out, all the while visualizing the outcome. as you go on in magic you could write on the candle, add symbols/runes, anoint it with oil, say a chant, and so on. but the most important thing is the ability to charge, focus and ground energy.
