(Dennis and his wife Crystal)

 

I recently read Today Is All You’re Guaranteed by Dennis Callaghan, who many of you know. It is a short, thoughtful, and impactful book that stayed with me.

 

Rooted in his experience surviving a horrific plane crash, Dennis shares reflections on courage, relationships, and the tendency we all have to wait for the “right time.” His message is simple and powerful: don’t wait - it doesn’t overwhelm, it invites reflection and action.

 

It’s a meaningful reminder — personally and professionally — that the conversations we’re putting off, the ideas we’re sitting on, and the risks we’re hesitating to take… those are the moments that shape our lives.

 

I’ve had the pleasure of knowing Dennis, and this book reflects the same authenticity and perspective he brings to life. Glad to see his message being shared widely. It is available on Amazon in paperback or kindle. I highly recommend! 

 

Excerpt:

Today is all we’re guaranteed.

Most people live as if life is long.
They postpone decisions.
They avoid difficult conversations.
They wait for the right time.
But life rarely works that way.
After surviving a plane crash in 1989, Dennis Callaghan began seeing life differently.
This short reflective book shares the lessons that followed — about courage, independence, relationships, and the quiet decisions that shape a life.
You don’t get unlimited rehearsal time.
Today is all you’re guaranteed.
Use it.
