There is a way, if you dont mind "hiding in plain sight". I have advised a few people to try this and it seems to work.
Simply, I have not met a pagan who was not "green". Probably the best test for being pagan is the love of Mother Earth. I dont know where you are but is there a place in the "green" which strikes a chord with you ? Somewhere that makes you feel uplifted ? Assuming you have, this could be your Special Place, preferably somewhere with running water. Start observing your "place" - the flora and fauna, the weather patterns, the geology, everything you can think of
but especially the changes with the seasons. Make a note of what you see. This is the beginning of your Book of Shadows.
If this makes sense, you might like to put together a simple altar - a flat piece of rock perhaps - and [again, up to you ] make a dedication to The Lord and Lady, or Mother Earth, or ...... Use words that seem right to you.
One key skill to develop is the ability to meditate and practice this in your place. You will start to notice things that have been unseen so far [ put them in the BOS ].
This could be the foundation steps of your Path - sort of Pagan 101.
No chants, no overt ceremonial - it will all be in your heart, soul, and spirit.
Best of luck !
