Well done for sharing your mistake. As you have learnt a lesson and shared it here, others will learn from it as well. It is sometimes very hard for others to admint their mistakes because of pride.
Experience is a best teacher and it easy for us to learn as we accept the mistakes we make. But if you let your pride overpower ,you will never learn from your mistakes. Even our experiences can help other people to make a wise decision to make sure not make the same mistakes.
agree, indeed we must learn from previous experience. because it is very important for us to change our mistakes for the better. so we have to learn diligently again, like reading about information and making decisions appropriately. whether the work is good for us or not.
