You're going to hear a lot of people say this: learn and practice the basics. The basics are meditation, learning to focus, and energy manipulation. For any type of spell work, you need focus, and to be able to direct your energy and the energy around you into your spell. Try simple meditating, do it every day for about 10 minutes at first, then gradually increase the time. You don't have to completely empty your mind, just learn how to quiet your thoughts and focus. Feel everything around you, the wind, the energy and just relax. In time, connect with the energy, feel the flow of energy inside of you and around you. Learn how to raise energy and ground energy.
Hope this helps
