Learn the basics, if you have not done so already. They include (but are not limited to) Meditation, visualization, grounding, centering, Sensing and direction of energy. There are posts on them here in the forums. Practice as often as you can. Work on positive affirmations to help with your magic (I am strong, What I do will work, etc) and believe in yourself and your workings.
Everything else depends on what you want to do with magic. Blessings on your path
