For me my day at begins before I get to work. I prepare myself mentally because work can be stressful some days. So make sure you are rested. When I get to work I make sure my work area is neat and I start planning ahead. Without planning and a neat work area, you can get stressed out way too early when you’ve got a long day ahead. Be positive because someone else was working your area in the previous shift. They may not have the same ethics as you do.
