The best time to plant a tree was 20 years ago. The second-best time is now.
In order to achieve consistent results, and to maintain our focus on each and every project, we keep our project priorities simple:
Remember the Customer:
Every project is going to be different and present unique challenges, but the one thing that we should count on is that our clients are going to be passionate about the finished product. We need to acknowledge and welcome the fact that we would have the same expectations for our own home.
Clean Job Site:
We are going to maintain a clean job site. We have to hold our trades accountable for it. We want the appearance of a project site to communicate to our clients, their neighbors, and anyone else that details matter and we focus on the little things.
Communicate:
Do not assume that everyone involved in a project knows what you know, take the time to communicate, ask questions, seek confirmation that everyone is on the same page.
The Theory of Broken Glass, Explained

It is very easy to let a project get messy, things happen every single day and there are multiple people from multiple companies working at a project site each and every week. As the builder, we must hold ourselves and everyone that works for us accountable to the same standard.
Once things get messy, they tend to stay messy.
A messy job site tends to influence and amplify bad behaviors, whether that be the mundane act of throwing trash away in a bin, or the meaningful act of connecting an fan duct in a tight attic space — for example.
We cannot let the appearance of a job site communicate to anyone that we do not care about the little things or they will assume that we are not paying attention. By focusing on the little things, the big things will take care of themselves.
