In this episode of No Bullsh*t Talks, we sit down with Clair Heaviside, co-founder of marketing agency Serotonin and ultra-marathon runner, to talk about the underrated power of resilience, discipline, and entrepreneur health.

Clair didn’t just build a successful marketing agency - she did it while running 13 miles to work every day. We talk about the mindset required to go the distance in business and in life, and why physical discipline fuels entrepreneurial performance.

This one’s for the founders who are tired of quick fixes and want the truth about what it really takes.

• Building mental and physical resilience
• How to lead when things get hard
