When our teachers make a small mistake like a typo error, don't all students point it out, but most of us don't even thank them when she teaches well. We, humans, practice always pointing out mistakes, and even I do, but we never appreciate things. Look at nature; we never understand its beautiful branches but point out the dry flower.
In the same way, we all don't notice what we have but see what we don't. We have a family, a home, a school to go to, books, fancy pens, and clothes to wear, but still, we eye the things we don't have. Like a pair of shoes, we don't appreciate that at least we have feet. Have you ever thanked God for giving you a healthy and happy life? Have you felt gratitude for having a beautiful face, hands, and legs? We think it is normal, but it's not. Even giving birth in this world is a blessing.
