ATTITUDE > EVERYTHING

What is
0sunni?

I’m JAE JUN SUH, a father of twins. I write about starting again, raising children, and finding our own way through everyday life.

Say it Young-soo-nee.

In Korean, the number 0 is read as “young” (영). The name comes from 0순위, or “zeroth priority.”

For me, Priority Zero is the foundation that helps me start again when things fall apart, without giving up on myself.

Doing it anyway

The strength to do what needs doing, even when you don’t feel like it.

02 — ABOUT JAE JUN SUH

I write.
I’m still learning.

I spent 15 years in Australia. Now I live in Korea, where I raise twins, sell cars, train, and write.

A day I raised my voice at the kids. A plan I didn’t follow. A person I judged too quickly. That’s where my writing starts.

When someone’s experience changes my mind, I revise the books, too. These are notes from a life still in progress.

Talk with me on Threads

JAE JUN SUH

A hello from Korea

I'm an ordinary dad in Korea who finds joy in learning about children's education.

I talk with experts on Threads and sometimes meet them in person to learn from them. Little by little, I bring what I learn into Priority Zero. Discovering new ideas and trying them out is a big part of what makes this so enjoyable for me.

We may live in different places and speak different languages, but I'd love to meet more people who share this care and want to learn together.

Come say hello on Instagram or Threads. I'd love to hear your thoughts and experiences, too.

A friendly hello or a follow means a lot and encourages me to keep learning and creating.
