I liked parts of the job itself, mostly the driving aspect as I got to listen to music in my own car while working in a way that was effective for me. That was the part of the job where I felt the most respected and trusted to do my job on my own terms.
What I wish was different
I wish I could have taken on more deliveries, as having that responsibility to do my job effectively on my own terms was empowering and gave me a sense of fulfillment.
Advice
Look up when your particular location has the most customers and when the most deliveries come in, if possible. At my location. I got more deliveries when I worked during lunch hours.
