I wish I had known this sooner.

If you work hard enough to achieve your dreams, you will eventually face conflict with the people closest around you, who met you under different conditions. As listening to your newest trials, tribulations, challenges, and ideas will wear them out, usually for no monetary reward.

Under this situation, the person(s) close to you may find it easier to speak quick words of pessimism about your idea or vision, as means of not having it consume their time, while still protecting the friendship. In other words, they love you, but not your idea. And would rather keep you around, by letting it die.

When you face this situation, the best course of action is to acknowledge that your idea is taxing the relationship and their time, and to treat their pessimism as purely their survival mechanism.

The wrong way to face a close ally's criticism, is to treat their pessimism as the authoritative judgment of your idea. Because you're not really asking them to effortlessly buy it as your fresh target audience. This whole time you've been asking them to invest their time (for free) in a vision that you have not yet brought into this world for them to see.

Take a step back, and let the relationship return to the conditions under which it originally developed, and you'll be surprised when one day, they come around. But remember, they’ll never do so, until it’s clear that your idea no longer needs them.
