So for example at Teslawe've never spent any money on advertisingWe put all of the money into R&D and manufacturing and designto try to make the car as good as possibleAnd I think that's the way to goFor any given company, just keep thinking aboutare these efforts that people are spendingare they resulting in a better product or serviceif they're not, stop those effortsAnd then the final thing isdon't just follow the trendsYou may have heard me sayit's good to think in terms of the physics approach from first principleswhich israther than reasoning by analogyyou boil things down to the most fundamental truths you can imagineand you reason up from thereThis is a good way to figure out if something really make senseor it's just whatever somebody else is doingIt is hard to think that way. You can't think that way about everythingIt takes a lot of effort, butif you're trying to do something new, it's the best way to thinkAnd that framework was developed by physiciststo figure out counterintuitive thingslike quantum mechanicsIt's really a powerful methodAnd so that's, and then I think there's a final thing I will encourage you to do
