Identifying a “need” isn’t enough:
People need to lose weight for their long-term health, but most don’t. (In the USA, over 68% of adults are overweight or obese).
People need to switch to environmental transportation options to reduce air pollution, but most don’t. (Fuel emissions from private vehicles continues to rise)
However, there are successful products that help people lose weight and switch away from fossil fuels. Their secret? They’ve put their products in a package that people want.
