I just had a conversation with someone I met from another community who also coaches others to live the life they want. Something that called my attention was that he learned a method that consists of 11 steps, where through smell he can reveal someone's personality, hidden habits and more. I too believe in the use of our senses as a self discovery tool but hadn't heard of such a thing like that 11 step method. An activity I'm familiar with involves touch. Long story short, I use custom made masks as a self discovery tool. I've used it with people I know well enough and it's not a method I've thought of using to introduce myself as it requires a high level of trust.
Is there an unconventional tool you've used in your work, whether it's coaching or any other line of work that has worked for you and your clients?
