Like with the gardening and cooking example above!
You might be able to build a perfectly wonderful garden, but that doesn't mean you can use the vegetables you carefully cultivated in any meaningful way in your kitchen to cook a healthy and delicious meal if you can't cook at all (but you can still share the vegetables with your neighbors who might share their cooking with you)! :)
