1) One of the biggest career decisions you'll make is who your life partner is (should you choose to have one). - - We should tell little girls that, while spinning tales of happily ever after. Everyone doesn't want or need a 50-50 partner, but some of us....need it like water.
2) When the opportunity presents itself, always sit at the table. - - I wish I had this explicit thought before now, but its something I've generally tried to do, and hopefully I'll have many more tables to take a seat at in the future.
3) What would you do if you weren't afraid? - - For one, I'd likely have not only taken a seat at the table, but spoken up more often too. I'd do most things without so much thought regarding how others MIGHT mis-perceive my intentions.
I think I'll read Sandberg's book when I get a chance.
