Yes, your greatest misery can be your greatest happiness. And your greatest happiness can be your greatest misery. It is a universal truth that every human asset when taken to extrems will become a human defect.
A few examples-a mom who has the asset of giving time to her children can be a well-balanced and loving mom. But, if she allows her asset of kindness and love to go to the extrem she can be a mom who gives too much and then spoils her children.
An individual who spends time and energy taking care of his/her physical body can be physically happy and healthy. However, if this individual allows his/her asset of caring for his/her physical body to go to the extrems s/he can become a body obsessed person who does not develop her whole self.
A person who has the gift of gab can entertain and attract friendships and favorable public attention. But, if this person allows his/her asset of gab (communication and small talk) to go to the extrem s/he can become too loud and over bearing and actually push others away.
The lesson is...be balanced. Don't let your greatest happiness grow to be more than what it should- it absolutely will be your greatest misery. The good news is - if you know your greatest misery-you are fortunate-you can usually balance it in some way and allow it to become your greatest happiness.
