My son is now 28 mos old and I'm still trying to find the right balance and figure out how to do 'everything'!!
Basically, if you are married, be sure to let your hubby know that you do need (and expect) him to help. (If you aren't married, take up offers from family/friends to help - either by keeping baby company so you can do it, or to help with the housework.)
Realize that something has to give - especially early on. Housework will always be there - it's okay to not get it all done. Unfortunately, "me" time also tends to be less - but you can learn to still do what you need to do. (For instance, if me time is working out - you can see if your gym offers child care, or find/borrow a jogging stroller, take a baby & me class, etc.)
With work, realize your limitations - be completely organized and handle your tasks, try to make it where you aren't staying late or bringing work home (that is sometimes inevitable, but it does add to the guilt when it's taking away from family time or other things needing to get done).
Definitely figure out the chores and shopping and determine who will do what. Do what you can when baby is sleeping - but also realize that if you need a break, to take it. You have to take care of yourself, too!!
Best wishes and know that it does get easier....but it doesn't necessarily mean you find your 'ideal' right away! As the baby grows and changes, your schedule with the baby changes, too. (For instance, he may be content in the swing now so you can mop the floors - there comes a point when he recognizes you're not in the room or wants to be down, and it's not quite so easy to get that little bit of time for whatever task...) Be as flexible as you can, and even when you come up with a plan/schedule realize it can always be changed if it's not working for you.
