Life is abundant and we have many gifts from God. We are very lucky to have born on this earth as a human being. Most of us have got what is needed to live a good life, yet we ignore all of it and feel sad. Sometimes in life we need to see from other person's eyes to appreciate what we have. Most of the time we value what we have after it is already gone. So instead of valuing after losing it, let's try to look at them from the person who does not have it. Then we might be able to feel grateful about those gifts.
1) Eyesight - Try to feel the pain of a blind person who cannot see the beautiful nature and has to be dependent on other people or a cane to even walk on the street. A blind person cannot see the expressions of his closed ones. He has to make out only from the voice whether they are laughing or crying. He cannot decide whether to buy red shirt or green shirt as they both are the same for him, black. We should be grateful for having eyesight to see this world, to enjoy this world.
