Tip? Don't think YOUR MARKET / YOUR COUNTRY is "a special case. The rest of the world is wrong"...
Particularly aimed at the S. African gent. If I had a pound (call that a Rand) for every time I'd heard some rookie telling me "Ah, your advice/training etc. DOESN'T apply to me because my market, this country or that product, is different from the rest of humanity..." I'D BE VERY RICH. In fact, I am very rich and I've sold all over the world.
