Every idea may be wrong.
It doesn’t matter how strongly you believe in an idea, you should always test the idea.
Are there facts that don’t fit with the idea?
Are there better interpretations?
Are there ways the idea can be refined?
Good ideas last and survive the test of time.
Poor ideas end up being refined or dropped altogether.
Never be too attached to your ideas that you hold on to them after you know they are untrue.
And remember, everything is an idea.
