We are often happy to gain something but we should always remember that in every gain, there is loss. Likewise, we may not like the loss of something but if we are wise, we realize that in every loss, there is gain. The job lost today may lead to a better position to be gained later. A mistake can lead to the loss of something, but we can gain the wisdom not to make the same mistake again. Remember, patience is the greatest virtue. It is the constant ebb and flow of the Dao.
