A simple way to tell if you really care about an idea is whether you care enough to seek feedback on it.
Most of the feedback you’ll hear won’t perfectly validate what you’re trying to do – and that’s okay. The goal isn’t validation.
Feedback helps you uncover weaknesses, refine your argument, and keep iterating until you have the strongest possible version of the idea.
That willingness to endure discomfort – to open your thinking to scrutiny and still keep going – is the clearest sign that you actually care.
