What's your life like?

May be I have done this blah blahing before but today I had to write this down again.
My life these days has settled in to a routine which sounds and looks ok but is very boring in detail. To summarize my any day, I spend 12 hours out of home( 10 hrs office +2 hours travel time 7:30 am to 7:30 pm) , 9 hours of sleep (9:30 pm to 6:30 am .. Something I cannot sacrifice or reduce for whatever the reasons be) and 1 hr of cooking(7:30 pm to 8:30 pm) 1 hr of tv(8:30 pm to 9:30 pm) . So except for the calender date there wouldnt be any difference between yesterday and today. But there are some days , for someone else's last minute planning, my routine goes for a toss. And am like so obsessed with my routine that the very minute I see a possibility of someone disturbing my routine , I get frustrated and today was one such days. A conf call was scheduled from 6:30 to 8 pm at office and I was supposed to attend it. It meant, I would reach home at 9:30 and lose out on 2 precious home hours. I just made some lame excuse and skipped it. But then there is this guilt also that I shouldnt have done that, I shouldve attended that meeting, it was important! I think its every working woman's dillemma.. neither get a 100% job satisfaction nor the 100% home maker satisfaction.
But to put it in the other angle, I have started hating this routine also. I mean, this is not what I want to do in my life. Do I sound confused? At this point I really am.. I can't quit the job because I got used to it and have also got used to the financial independence and dependence on the good sum that gets deposited every month in my account. Its just too addictive! But its not really the case that am really happy spending 12 hours of my day for this leaving everything else haphazard. It's only when we have those friends for lunch or dinner during weekends I realise how much the home needs my attention and time. When I see other women who are happy home makers, I feel jealous, I also want to quit my job, but when I really think of it, am not sure if I can be happy sitting at home all day doing just that!!
May be its really time I seriously think of the other options I can be happy with... do something which gives me satisfaction and a control over my life and my time.
