I was FABULOUS parent until I actually became one. You might want to think about that op. 
My child was going to have a routine. My child would go to bed by seven and sleep through. My child would be taken out every day to do stimulating activities. My child wouldn't tantrum because I would distract them. My child would have impeccable behaviour in restaurants because she had been eating out since birth. My child wouldn't scream because frankly, I wouldn't allow it....
My child had other ideas. Because that's the thing with children. They are individuals with their own minds. You can try everything and still not succeed. And my child is normal, she's a fabulous mix of spirit, good manners, stroppy attitude, happiness, good behaviour and bad. She screams and is quiet, she sings at the top of her voice, or whispers. She runs on tippy toes like a fairy, she stomps like a giant. She runs EVERYWHERE, unless speed is required, then she turns into a snail. She is good, naughty, loud, quiet, obedient and disobedient depending on her mood, the trousers she is wearing, the colour of her crayon, the cereal she has for breakfast.... She is three.
As I said, I was a FABULOUS parent until I became one. Now I do my best to be a good enough parent. So sometimes her behaviour is frankly crap, sometimes she screams and stamps about, some nights her mantra is 'sleep is for the weak', sometimes I end up crying from sheer exasperation with her behaviour.
Yet I know she is a happy, confident, clever child who knows she is loved, who is just being three and that is good enough for me.
There is nothing on the planet that prepares you for having a child of your own. I think you are in for one hell of a shock. There is a reason babies are born tiny and cute... Because if they were born as toddlers, with toddler behaviour from the start we'd probably want to give them back. The toddler years are FAR more difficult and exhausting than the baby stage. Think about that when you are feeling smug and dishing out advice based on zero actual experience....
