Carry an conspicuously large, otherwise nondescript, empty box all day. See how it affects my day.
People might help me out, or engage with me differently. They might just think you’re particularly strong, or industrious.
Note
I was building a Christmas present and it came in this massive box. I required help carrying it. When I finished, I returned outside with the box but since it was empty I could carry it myself. Someone looking purely externally would have to conclude either me and my carrying partner were faking the initial weight, or I was unusually strong.
The box itself was unchanged.
