From my experience, those that made CO gave up too much in the other areas of their life.
Bingo. This goes along with rob's post: For many of us, choosing between family/happiness and chasing CO & beyond is a no-brainer.
I love what I do, and I truly love my current assignment (I consciously chose
happiness and
job satisfaction over taking shit jobs that will enable me to better climb the ladder). However, if I'm ever put in a position to choose between my family and the Corps, it's non-negotiable. The Corps survived for 221 years before I enlisted, and it'll sink or swim for decades/centuries without me.
My family comes first.
In the meantime, I'll continue to do all I really can do in this life: Go into work every day and give it my best. Hopefully that's good enough. If not, and the Corps decides (as it continues "Right-Sizing") that I'm not a "straight shooter with upper management written all over [me]," so be it. I won't be bitter - I'll retire knowing that I gave it an honest effort for two decades (over half of my life), did the best I could for my Marines (and, in my current assignment, my Sailors, Coasties, and Allied bubbas, too). I'll also retire relatively young, with good mental and physical health, and, most importantly, a happy, healthy, and intact family.
