Just like every thorn has its rose. This is the duality of life. There is good and bad in most things. Without the bad, do you really appreciate the good?
Likewise, with the things that make our life pleasurable. Too much of a good thing and the good thing becomes ordinary - it loses its appeal by virtue of becoming humdrum. We often end up taking it for granted, then.
I remember when I was about 10 years old, asking my mom why we couldn't have my favourite dessert every night. Her quick reply, "Because it wouldn't be special."
My mom was wise. She knew that serving that dessert on a regular basis would no longer make it a treat. It seems to be a condition of human nature that when those special things become everyday, we take them for granted and they lose their "special" designation.
This applies to people, too. How many of you are taking those who love and support you for granted?
With mindfulness or attention, you can become aware that this is happening. Remember to appreciate and value those good things and people in your life. In so-doing, you have activated the power of your heart, which is the key to undressing your stress.
