Far too often, perception is thought to be reality. Just as these tracks don't actually connect in the distance, a nice home and car doesn't always mean they someone is wealthy, well behaved kids in public doesn't necessarily mean a happy home life, lovey-dovey pictures on social media don't solidify a perfect marriage. Trying to compare your life to others in this way is looking on with skewed perception. Ask what God wants for you and base your reality on that.
