I dare say you haven't had much practice

"There is no use trying." said Alice; "one can't believe impossible things."
"I dare say you haven't had much practice," said the Queen. "When I was your age, I always did it for half an hour a day. Why, sometimes I've believed as many as six impossible things before breakfast."

Lewis Carroll
