Be really worried whenever your strategy is 'this and that' instead of 'this, not that.' I would always bet on an entrepreneur who's saying 'it's this, not that' — even if they're wrong, because they'll find out that they're wrong and be able to pivot. When it's 'this and that' they'll never know if they're wrong because everything will just be half-baked execution ... Was the problem the execution or the strategy?
