People love to give you their opinions. Especially friends and family. But what do they know about the topic? When you’re starting something new you assume that everyone knows better then you. After all you know nothing and everyone seems to be so knowledgeable.
Their not lying to you, but they haven’t done the research either. Think of the last time you gave someone advice, what did you base the information you gave them on? A Youtube video? a post? and email? You have to develop the habit of researching what you see and read. If you make a mistake it’s still your mistake.
Blindly trusting information online is like asking a fat person for diet advice.
