That's what I tried to teach guys at TGCL when I was there years ago. To be a big producer like I was, it's not what you do on the job, it's what you do between the jobs where you make up a lot of time. Proper routing. Pre assembled flags and stakes, not stopping for a pop every five jobs and not calling the GF all day. Lunches? Forget it. The "job" or landscapes take a certain amount of time depending on what you are using to do the work. That's not going to change much. Unless you're cutting corners.
