Things for entertainment aren't needs. For example, designer clothes, the new iPhone that just came out, fancy dining, that expensive shirt that has the same model somewhere cheaper, and sports cars are all wants, not needs.
Needs are like water, a shelter to live in, food, clothing, and running electricity. Water is essential for survival, since you could die of thirst in 2 days. A shelter will protect you from insects, weather, and uninvited guests. Living without food will kill you in 2 weeks, as you need food for energy and so let your body repair itself faster if you got injured. You need clothing to keep you warm and to cover your private parts. Running electricity is needed because electricity makes most of your needs easier to acquire.
I hope this helps! Good luck!
