@mcusyd hello!!
im sorry for such a late response really.
to answer your question; the only way to start practicing wicca or witchcraft is well, by just starting it! try to incorporate little parts of your practice in your daily life. like, bless the space you stay in. maybe sage the house and feel the positive vibes around you. meditate daily and try to become one with nature and all the forces! the possibility is endless!
but before you start, make sure you read and know a lot. KNOW what you're going into and learn protection spells to protect yourself from all the negative energies and spirits.
if you have any other questions, please feel free to PM me!
blessed be and good luck! c:
