Newbie landscaper here: what's a typical day like mowing 20 properties with my John Deere 1-series?

been in landscaping for like 3 months now, mostly residential lawns with a mix of grass types, and i'm charging $50 per cut to start out. wake up at 6am, load up the trailer with the mower and blower, hit the first few stops before traffic kicks in, but by noon i'm beat from the heat and edging all those damn flower beds. anyone got tips on not burning out on the repetition? saw a thread on r/lawncare about batching routes but not sure if it applies to small crews.
