Research the laws of your country on magic, some countries still outlaw the practice.
Learn what magic is, what it can and cannot do, and how it works. This will help you to separate fact from fiction as you continue your journey.
Learn about meditation, grounding and centering, energy work, and visualization. This will help you in your practice.
Research different forms of paganism and magic to find what is right for you.
Understand this is not easy, it requires work as there is no single authority on right and wrong.
Look into yourself and find what you feel is correct when it comes to morals and ethics.
No one on this path is an expert, those who claim to be are either fools or con artists.
Practice. Be mindful of events around you and see the magic in them.
Patience. This is a lifelong path, don't expect success immediately.
Education. Never stop learning. The more we learn, the more we understand, the better we get. This holds for all things, in my opinion.
Know that as you learn you will begin to think you know nothing. That is fine, most of us have been there. There is no shame in 'starting over' often you pick up things better the second, third or fourth go round.
After time learning, you will come spells.
