The owner's energy is the shop's energy
Whatever the owner brings into the building in the morning gets multiplied across the team by lunch.
Walk in calm or don't walk in yet
Five minutes in the truck before opening the door, every day. Reset before contact. The team mirrors the owner's first 30 minutes.
Don't dump your morning on the team
Bad news, frustration, last night's drama. Process it before the huddle, not in it. The team can't carry the owner's emotional weight and the shop's work at the same time.
End the day, don't drift
A clean end of day (last text, last email, last truck check) prevents the owner's night from leaking into the next morning. Boundaries are leadership.
