Practice drawing energy from the elements. Feel it in you. Cast a circle. Feel the difference. Practice pulling and drawing up your own personal energy. Practice running that energy down your arms into a charm, with a specific purpose. And I would second the protection suggestion. Charm a stone or amulet for protection from negative energies outside of you. Also practice meditation daily and finding your balance. Remember as you grow stronger and begin to practice spells on a regular basis, that you first need to be balanced. You also need to remember to think very hard about what you want. Do you really want it? What could be the repercussions of how you phrase it? Hope that is helpful.
