This may be a surprise, or perhaps a relief, but how related or connected your modalities are has no effect on finding a through-line element as a Multi-Hyphenate. ie, yoga + reiki vs design + podcasting.
Whatever your specialties are, you define the connection - which becomes something I like to call, your North Star. This is your core message, theme, or pathway that brings a sense of cohesion to all that you do and provide. And it allows you to assemble the use of your various skills in a form of service that aligns with your zone of genius.
So, to find your North Star, I suggest simply grabbing a piece of paper and mapping it out. This may sound a little cringey, but just try it. If it doesn't give you the answer you're looking for, it will at least help you get closer to your through-line.
