I have four daughters ages 4 to 14 and the one thing, without a doubt, that kids did for me was that they help me to slow down and appreciate the little things in life. If it wasn't for a my daughters (and my wife, to a lesser extent) I'd probably do nothing but work and sleep. But they keep me grounded in the rest of the world. And something as simple as a few minutes watching a show or playing a game together brings me more joy than it ever did before I had them.

As for you questions; yeah, it'll can change your priorities, inspire you to do more or do different. And, as you can see in the rest of the comments, having a baby instantly requires everyone to give all the advice they wished someone had given them.

My advice, ignore 99.9% of what everyone tells you. Doing that is what kept my wife and I sane.
