Trust yourself, be kind to yourself, keep a diary or make little notes about the things you love and hate because it all changes so fast and it's precious time even when it's relentless and hard. You'll forget so much, even stuff you think you never will.
Also, so much good advice here and elsewhere -but not all of it will suit you and your baby. Read, or listen, take what suits you but have no guilt about letting go of the rest.
You are not a failure if your child won't settle in a cot/nap consistently/eat widely/potty train at the right age etc etc. it's just life- you're doing your best, so are they.
It's great to plan your birth and discuss with your partner so they can support you and you can feel prepared. But things rarely go exactly to plan and that's ok, it's not failure, it's a triumph to bring that baby into your arms, however it happens.
Songs and rhymes are so wonderful for you and them, plus little routines and rhythms. I did sing and sign with two of mine and it was amazing.
Definitely rest rest rest in the first weeks, let others help, have no expectations on yourself except to enjoy your baby as much as you can.
When you start weeping for no reason in the first days/weeks/months it's probably just ormones and exhaustion, try to let it just happen and not worry it will be forever. But if it feels too much, ask for help, speak to your GP or a friend.
And oh my goodness, just savour as much as you can. It's magic. You'll be brilliant. Have fun!
