Forgetting to remember

I told my husband I want a tattoo. Just a small one of a pink ribbon on the inside of my wrist. He asked why and I told him that I want to always remember. When I went through cancer I arrived on the other side with a new appreciation of life. And I asked the question, "How does one keep this feeling? How do I prevent life from sneaking back in and taking over?" Or something to that effect. And now I am living that. I am forgetting to remember that I have been through something that will forever trump dirty dishes in the sink, or my son's messy bedroom, or the drive to work, or the car not starting, or my boss chewing on me, etc. I want to always remember.
After 9/11 when everyone was nice to one another and spoke kinder and softer and flew their flags......remember that? And then slowly we started to forget that we are ONE nation......together......it hurts me that we forget to remember that we are not the enemy of each other. I don't want to forget to remember.
It's so hard not to let life take over. So I want a tattoo to help me remember. But my husband doesn't like the idea. I just am not sure he understands.
