Jen, hope you have fun! If you ever need WP advice, shoot me an email :-) Be happy to help. It is pretty easy when you get the swing of it.
On the topic though....
Maybe I got it out of me early on. I wandered from my late teens through like early 30's before I found what I wanted. Growing up I never had roots. My Dad moved when bored. We never owned a house. It ate at my Mom so badly and profoundly affected her health - he was self employed and they never had good health care. So in my early adult years I found myself mimicking my Dad. Even after I had kid 1 at 24, I kept wandering. He just came along, him and I.
I met a guy who grounded me. He has helped me craft a life for myself. I have lived in a house we own for 9 years, the longest I have lived anywhere. Slowly I found myself wanting more. I built a garden. I painted. I added doors I wanted. I had 2 more boys. Does my mind wander to the days when it was just me and the oldest? Of driving away and being free? Yes it does. But then I realize I don't NEED that. I have a happiness with what I have now I hadn't had before.
When I watch Walker and Alistaire growing, I know my place in life is right. It isn't about reproducing, it is I wanted my 3 boys more than anything else. I have a brother and 2 cousins, born 2 years apart, same age as us. None of them have kids. We have all turned 40 and 42 now. Do they miss not having kids? Maybe and yes.
I still hike and backpack...but my burning desire to be out there all the time has dimmed. And that is OK. My garden calls to me...and so does picking berries to feed to my little ones, to teach them to love the land.
