Picking one product that simplifies my life was SO EASY.
While I love technology [especially my iPhone] I am still a huge fan of paper & pencil when it comes to planning out my life. So the one product that simplifies my life is hands down my Emily Ley Simplified Planner
I used a different brand of planner for several years before and made the switch to the Emily Ley just this year. The lightweight design, white space & the mission behind the planner made it the perfect addition to my life.
I highly recommend the Emily Ley Simplified Planner if you are still a paper/pencil person when it comes to organizing life.
