For everyone who says they don’t know their purpose in life - I’ve spoken to hundreds of individuals over the last few years, exploring this question for and with them, and together we have found an answer in almost all cases.
In my experience, everyone knows what they want deep down. Sometimes their vision gets a little clouded, or blurry and they just need a little help and nudge to see it clearly. It’s a matter of asking the right question(s), in the right way at the right time.
