If you have presented an idea to someone you should never ask for an opinion, but for advice.
"When you ask for an opinion, the person takes a half-step back — you’ve asked them to introspect and so there is a distancing. But if you say, 'what is your advice,' they take a step towards you and it triggers a co-operative mindset and they are more likely to support your idea."
- Robert Cialdini
