In this Serenity Now for Entrepreneurs episode, The Serenity Sisters sit down with Tatsuya ‘Tats’ Nakagawa, CEO at Castagra and host of the Roofer Reflections & Specified Growth Podcast.

We discuss what lessons Tats has learned from being a serial entrepreneur, including many ups and downs along the way.

Having built successful service and product-based businesses and fighting many challenges, Tats has a wealth of experiences to share with fellow entrepreneurs.

Tats also tells us about an excellent test he has used to evaluate business ideas. The Serenity Sisters were genuinely intrigued by this “3 am test,” but you’ll have to listen to the full episode for a full explanation!

This is a great episode for any aspiring or current entrepreneur to listen to for lessons learned on the path to becoming a successful entrepreneur.
