Sucess?

What's your best tips for a first time mom to make sure she has success? I DO NOT want formula. I have put in my mind thay formula doesn't even exist. . but what if my birth is just the worst and the last thing I want is more discomfort trying to get the right latch, ect. What if when I get home away from the nurses and lactation nurses and I just feel like I can't do it anymore? I'm perfectly okay with pumping! I actually hope I'll be able to pump (I think I read after 6 weeks?) so my husband can do feedings too.
