The power of question

If we tell someone what to do, we may get resistance.
If we ask a question, it invites a response.

I know this is difficult. However, if we create resistance, we're wasting energy.
So, if we want to convince people, shouldn't we use the 'question' form?
And then, even better a 'nice' question?

Instead of:
- You should do it this way!
Why not say:
- Shouldn't you do it this way?
Or, better:
- Shouldn't we do it this way? (using 'we' works better than 'you')
Or, even better;
- How should we do this, to get a better result?
