This is good advice. Personally, I call myself a "founder" or "co-founder" over "entrepreneur."
For in-person interactions, whenever someone asks me what I do, I always just say I work for a tiny company that does XYZ. If they pursue and ask what I do for the company, I say I bounce around doing a bunch of things (which founders do).
