From the moment my doctors told me the tumor they discovered in my right breast was malignant, the blanket of security I carried around with me my entire life –- the myth that I always had tomorrow and the next day -– was suddenly shattered.

It’s one thing to physically battle cancer -– it’s grueling and tests your body in ways you cannot imagine -– but it’s another thing altogether to mentally take it on.

For me, that has proved to be the toughest fight, one I struggle with on a daily basis. Every time I have another blood test or doctor’s appointment, or when a dark thought enters my mind (Will I ever get to be a grandparent?), I remind myself that the only thing I’m guaranteed in this life is right now.

I've decided to not die before I die. I live better now.

I am a better parent. I yell less and cuddle more with my daughters. I am a better wife. I yell less and choose my words more carefully, remembering we are what we say.

I want to leave every room I enter better than the way I found it. I’m not saying cancer is a gift -– because if it was I would gladly return it -– but now that the box has been opened, so have my eyes and my heart.

I see how precious life is and how grateful I am to be right here, right now.

1) Laugh more.

2) Love more.

3) Yell less.

4) Remember the only thing you can actually control is how you react to life.

5) Acknowledge that there is no such thing as security –- it’s a myth -– so give every moment the precious attention it deserves.

6) Don’t die before you die -– we’re all terminal cases -– so start living. Do what you want, cherish what you love, celebrate what you have.
