Make a ritual

Over the years I’ve found that simple rituals before starting to write were the fastest way to get me into the right headspace to write.
Rituals also create a calm space to work in, something I really need to get into writing mode.
A ritual can be simple, like lighting a candle, or taking a moment to close your eyes and take a couple of deep breaths.
A ritual can also be elaborate, something like setting out your pen(s), opening your notebook, lighting a candle, doing some stretches, pull a tarot card for the day, to get yourself ready to write.
What kind of ritual can you create to set the tone for your writing?
