Evaluate ideas independently of who said them. Read books/blogs/tweets without caring about the history of the person saying them.
This skews your judgement. It will lead you to disregard the idea if you don’t like the person.
Take the idea at face value.
Don’t quote. If people ask you where you got your ideas, then of course you can point them to the book/person/resource.
Listen to music without knowing who the artist is. Consume art without caring who made it.
What matters is how it impacts and informs your own perspective and opinions.
