You can read the full piece here, but below are a few notable excerpts:

• I’m an early bird—so I try to seize “Juliet time” first thing in the morning. I get up between 5:30am – 6am and quickly scan my email. Then my priority is exercise… I’ve found that having a trainer come to my house on a Monday really motivates me—she’s knocking at the front door so going back to sleep is NOT an option…. On cardio days, I use the elliptical or spin bike for 30 minutes.
• My Day: Is a blur from the minute that I arrive in the office but that’s how I like it. I have the benefit of an amazing assistant, without whom I could not make it happen… On a Friday afternoon, I’m given the list of outstanding calls/topics/decisions that I need to make over the weekend. I carve out key moments during the weekend to do emails and return calls. During other windows, I turn my Blackberry off so that I can focus 100% on my children and my husband.
• My great friend, Sheryl Sandberg, COO of Facebook, shared with me a great tip, when we were both on maternity leave after the birth of our first child, to create key spreadsheets to help manage your home life.
• Condense your appointments: find a great salon that understands time pressure and can accommodate your schedule. I have a great salon near me that I can go to at the end of the day to have a facial, manicure and pedicure at the same time.  I’m in and out in 70 minutes. Not relaxing but efficient. Same for other appointments. I have acupuncture at 9.30pm at night. It’s a wonderful end of the day.

See. You can have it all. Just get organized. Plus, get a personal trainer who makes house-calls, some home gym equipment and a personal assistant at work. I really don’t understand why Gwyneth’s reader didn’t think of that herself…
