I'm the same - too technical by half.
I had to learn this 'emotional' stuff - that many words have 'baggage' attached to them. 'Heat' is at best an impersonal word - whereas 'warm' is comforting. We talk about being "nice and warm", of "having warm toes" - "I'll warm myself by the fire" and so on...
'Warm' has good baggage attached, 'heat' is suspect, 'hot' is undesirable (on a personal level). Most selling has emotion at it's core: the attitude of the sales-person, the type of packaging, presentation generally, including colours. Supermarkets spend fortunes on this kind of research.
Take the words used. If you're selling washing powder - then 'New' and 'Improved' are key words to use. But - if you're appealing to the natural food customer, then 'Natural', 'Original', 'Wholesome', 'Old-World' - those are the kinds of words they're looking for.
"Aunt Bessies Original Recipe Flapjacks" - with a picture on the label displaying a log cabin kitchen, with an old lady, spoon in hand. The customer is actually buying nostalgia - a tried and tested traditional product from their youth, or their grand-parent's youth. The fact that this stuff is churned out by the ton on a stainless-steel production line, and shipped around the country in huge diesel-engined vehicles is irrelevant (and would be undesirable for the customer to become aware of) - because that is not part of the product they're buying.
