Going back in time, what would you tell your (pre-pregnant or pre-mom) self?

First time preggo here, and I'm just wondering from you experienced moms of 1,2,3 etc kids, what do you wish you could tell yourself the first time you got pregnant? I don't want to sweat the small stuff! Please share anything you've learned, whether it be 'dont bother with expensive belly/baby lotions' or 'invest in some good swaddlers' whatever helps! Thank you!:)
