"Trying to get answers before fully considering the problem." "Being uncomfortable with not knowing."

These two things seem totally at odds to me and it's something I struggle with constantly. How do you ever know if you've considered the problem enough? If you come to a problem you cant solve and go to someone for help there's always a chance that person will ridicule you and put you down, destroying your motivation, because you didn't "fully consider the problem" in his eyes.
