First, go on a diet, where you eat less, especially less sugar and meat (please, no low-carb diets, as they're unsustainable). Use computer software to track your calories, and move to the correct body mass index.
Second, go on a budget. Pay down your debt and start saving. Start reading up on tricks to save money.
Wealthy western society has to cut its consumption, otherwise we're going to either overheat the planet or run out of resources in a hurry.
Sorry for the polemic today.
