Two words and four months of notice

Someone close to me was taking a green interior design course, and one class handed her two words that changed my career path before the night was over. I do not remember the whole lecture, just the phrase, and my reaction was immediate: construction itself could be rebuilt around that idea before anyone else in my market figured out how. I did not quit that week. I gave my employer four months of notice, finished what I owed them, and used the runway to actually build the thing instead of announcing it and scrambling. That became Tellus, a company whose entire identity I built around that one idea roughly a year and a half before the rest of the market caught up to it. The four months mattered more than the two words did. Anyone can have an idea in a lecture hall. Fewer people give real notice and build the runway before they jump.
