text: Some details of why you should get more than one persons opinion are that some people are bias with their opinion, for example one person might think that one thing is better to do just because that is what they do even though it may not be the best thing to do. Also some people may not have good advise for you if they never had to do something similar or they just dont know what you are asking them about. One more thing is that one person might just give you bad advise even if they dont mean to, so asking for lots of peoples opinions would be good so you have a higher chance of getting good advise.
