Well, the opinions of expert is very important and/or valid in the search of knowledge because they are the people who know the most, or the people that know more than others, as long as they prove what they are talking about, or arguing about, but not only the opinion of the experts is important, the opinion of the non-experts and everybody is also important, because they know their own things.
No one can learn everything and much less by them self. When you are searching for knowledge you are getting facts and truths for yourself, there have been people who have the time to develop their own 'thing', who became an expert, just as you will have developed your own 'thing'. We all have freedom of thought, for the most part, and that allows us to gain and exchange knowledge with other people, from those who have developed opinions, in order to gain even more knowledge, so that we may form our own opinion. Your time and energy can be focused on your next step in your plan by heeding advice and opinion from others and by not having to do all the research alone.
