Hakeemul Ummat Hazrat Mawlana Ashraf Ali Thanawi ra said;

“In seeking consultation with someone make sure of the following two things:

1. You have complete trust on this individual. That is, you are sure that he will advice sincerely whatever is most beneficial for you.

2. He (the consultant) has the insight (baseerah) in the field he is being consulted.

Tohfatul Ulema, volume 1, page 85

Most of us are negligent in point #2. We ask question regarding professional education, bussiness, marital matters, etc. from naïve pious individuals who do not have substantial knowledge & experience about these issues.
