It changes everything, absolutely everything. The love you FEEL for your child transforms everything. Now you have SOMEONE helpless and tiny that depends on you and only you. You look at him and KNOW that your WORLD is focused on him, on that PART of you.
When you become a mother, it's a COMMON thing that you just WANT to put every OUNCE of your being into your CHILD, which is a very BEAUTIFUL experience.
As a GENERAL rule, when your child, or anyone in the work force, doesn't KNOW what he/she wants to do, they should instead always be developing skills and competencies that will qualify them for the jobs that COMPANIES are most looking to fill and increase their hireability.
