My biggest challenge these days is trying to manage the stress with a calm approach. I think what my life has taught me in the last few years, is that you have to take it one day at a time. Perspective is huge for me. The two people I work closest with go from crisis to crisis, like a sine wave. I can't do that anymore. I too want the kudos of getting a really important project through with terrific results and successfully competing against our closest rivals. But mostly, I want to be with my family, be happy, and live life to the fullest.
I hope this approach to life isn't perceived as "not caring" about my job, something I worry about in the environment I work in. I work very hard when I'm at work and most nights for some time as well. But ultimately, I won't define myself by my job - I never have.
