You know the answer.
Listening to others is great and yet they often have their own agenda.
Look to their motivations.
Does self-interest drive them in some way to say what they have said to you?
Most of us are motivated by what we want and what we value.
Before changing your course of action, look at the motivations around you.
Why would he have said that to you?
And most of all, beware unasked for advice.
