There is meditation, for some it is easy and not so easy for others. With a simple search online or even in a book you can find guided meditations to help you start, or bring one in if you have done it before. They can be short or long depending on how long your need or want.
DIY what you can. If you have craft supplies and recyclables lying around you can get crafty. You can make different things from the items you already have. For example if you have pipe cleaners you can make a Brigid's Cross. A wooden tray that you do not use anymore can be used to make a portable altar.
Doodle/draw your own pictures. Write some poems. They do not have to be perfect.
Bond with your familiar. Whether yours is furry or scaly, take some one on one time to reconnect.
Check out a public ritual. There is a possibility that there’s one within 20 miles of you. Sites like Meetup.com and Witchvox can help you find “your people.” With the exception of women’s only groups or other specialty events, most public rituals welcome everyone and are usually free.
Share your knowledge and teach a workshop. Are you uniquely qualified in a particular branch of paganism? Maybe you know how to make brooms, or when it comes to the Nordic gods. Most event organizers are thrilled to have volunteers, and you learn as much, if not more, by teaching than you do taking a class yourself.
Memorize. It could be a song or chant. It could be information on a certain subject like numerology. Small or big, it could happen.
Get a potted plant, get a cheap dowel or paint mixing stick from a home improvement store, and draw your own godpole. (This is basically a pole version of a statue, for those who don’t know.) Put the little mini godpole in with the plant. You can bury small objects in the pot that you want to offer, or pour libations into the pot, and the plant will help with disposal (particularly if you are in the habit of offering fresh water on a daily basis).
Find stones outside. Get some cheap acrylic paint. Decorate your stones to take the place of statues, or elemental symbols if needed.
A word about cheap incense: often these are made with synthetic scents and chemical binding materials (to make it stick to the sawdust) that don’t fare well when burned. Heat changes both, and if you get a headache when burning cheap incense, you might not be smell sensitive, you might be sensitive to the changed bits of chemical that you’re not smelling but inhaling anyways. Be careful with super cheap incense if you have breathing sensitivities, or someone else in your household does. If you get headaches, don’t use that brand anymore.
