When you need something you usually want it.
Often, you want what you need.
When you need food, for example, you typically want food because your brain/body tells you you’re hungry.
But most people want things that they don’t really need…
People often want more and more possessions, even when having those possessions doesn’t improve their life…
We often use the words need and needing when we really mean want and wanting.
You always know what you want……
But you don’t always know what you need….
You are always aware of what you want (you know that you want some sweets, for example).
However, you are sometimes unaware of exactly what you need. (it is difficult to tell if your body needs sugar or specific vitamins for example.)
