In reading “The Defining Decade” by Meg Jay, I have learned that twenty-something are the important phase of the life. The better you plan at the age of twenties, the better planned your life will be in the years to come. Procrastination in taking life’s decisions will add the problems in the life. To jump-start a career and to choose family need planning beforehand and twenties are the age to decide because the benign impact of negligence in your twenties may throw people at the clueless position in late thirties and forties.
