When my sister and I were little, we would cut pictures of people and things from our mom's old catalogs and magazines.
Women and men sporting the latest trends became the moms an dads of the little 2D lives we created - on roadtrips, at our grandparents, whenever we were feeling creative. The moms and dads had 2 or 3 or 7 children (I think we wanted more siblings when we were young). A dog or two, maybe a cat. Fancy beds with fancier bedding. Perfectly coordinated furniture for our grand rooms where our families lived. All cut out, shiny and arranged neatly. So easy to believe, at the age of 10, that life simply fell into place with the snip of the scissors. Maybe because we wished our family had more. And maybe because we thought are parents just weren't choosing correctly.
But really, you can plan your life out as much as you'd like and still never get the shiny, perfectly life you've created in your head.
