I think you could make a venn diagram out of 'building the right thing' and 'building it right' and the intersection of the two is the sweet spot where a successful and sustainable product might land. Or, more likely, it's where one might gravitate to over time as the business matures. Even within that spot there's room to shift focus - sometimes you'll want to work on technical excellence, shoring up bugs, paying off tech debt. Other times it'll be a case of taking on a bit more debt in order to innovate. The proportions of building it right and building it the right way will shift but never so far as to abandon one of those principles.
