You are an auxiliary member of the team, if you follow them passively and read their ideas.
Discussion
Because their ideas and conversations are shaping your mind and making you less mentally free.
That is why, when you have a solution A and you read someone else's "better" solution B, for the same problem, you will often be tempted to alter your solution.
That might be a good thing, if their solution is truly better. But it means that you now have the same solution and nobody will have a choice of solutions.
What if someone comes along later and they have a problem that would have been solved by your "worse" solution? We will never know because you never built it.
This is how innovation dies a thousand deaths.
