It's pretty easy to ask questions.
For example, you can ask someone, "Do you want Ice Cream?"
Most would, of course, respond with an enthusiastic "Yes!!"
But. You can dig deeper.
"Will you pay for this ice cream? Why?"
"What if I set up a shop, at this specific location?"
"What about different types of ice cream?"
The ice cream exists because it is ice cream.
Validation has been established, so what makes your ice cream better than all the others?
