Those with the power of tolerance will be content and will make others content too.
When there is tolerance, there is also continuous improvement. This in turn brings satisfaction for the self and also enables us to become a source of support for those around too. This will make them content with themselves and with us too.
Let me take a thought to make it a point to learn at least one thing from all the suggestions that I get throughout a given day. When I keep this in mind I will be able to tolerate even negative comments very easily and I will find myself improving.
