Listen to others' tips and tricks. Give it a try, but always always listen to your gut. If it doesn't seem right, move on! Don't make yourself miserable trying to do something that doesn't work for you. A happy baby is made by a happy mama.
No matter what, you're the best mama. There are no absolutes to parenting. Don't let the judgments of others make you feel bad. And don't judge yourself against the standards of others. Like if breast feeding doesn't work out for you and your baby, it's okay. Being a mama is not a competition.
