Good luck! It's one of those life changing things: no one can predict how you'll feel about it either.
What I found helped me was to get all my ducks in a line: have a number for a physio who specialises in post natal care in case you need one
Ditto a lactation consultant just in case you need one

Ime Having a new baby and how you feel about it really depends on the kind of delivery you had, and how well you can sleep afterwards.
If you're in pain, or have had a long and medicalised labour you may find that the first few days are really miserable. You may change the way you sleep and not feel rested: I know I became a very light sleeper, and that was a big surprise to me. My brain went into overdrive to listen out for sounds from the baby, and I only dozed, never getting restful rem sleep.
If you have an uncomplicated vag birth, the endorphins may buoy you up for weeks. If you have a crash section, you may be too freaked out/ exhausted to enjoy the birth, and not get the rush.
Breast feeding, rather surprisingly, doesn't come easily to everyone, babies included, so it can be very uncomfortable, especially if you get mastitis. The girls here are brilliant for advice though. And a lactation consultant can solve a problem latch which may have eluded you.
Just be kind to yourself and your partner if you're not feeling the love.
Fwiw it's not obligatory you fall in love with our baby immediately: sometimes being exhausted/ on morphine/mastitis can do that!
Don't forget to take lots of photos, and to rest.
Tbh, I think babies are lovely, but toddlers are amazing, preschoolers and wonderful and kids are fantastic: the teen years await us, so am reserving judgement 
It's all good, just in different ways.
Hope it all goes well! Some good advice from previous posters- don't overload yourself is brilliant advice, I had a friend who practically went out to show off her baby before the placenta was born, and she crashed from exhaustion a few weeks later.
Take it easy and keep us posted on how you get on.
