Purpose vs. Passion

What do you say to someone who says “I get my purpose, but I don’t feel I have a passion for anything”. In society, we’re really being pushed to “Follow Our Passion”. Lewis Howes, Amy Porterfield, Gary Vaynerchuk, Tony Robbins, etc. So when someone says “I don’t know what my passion is” or “How can I find my passion? What activity/work/business should I be doing this my life?” – do you have an answer to that? There’s such a drumbeat about passion – I’m wondering if there’s a guiding philosophy you have about that.
