The single most important thing you can do for yourself in this process is to be open to it. Some of us come to Confirmation on our own, many at the urging of our parents or because it is what we think we are supposed to do as young Catholic. However you get here, know that if you enter the process with an open mind and HEART, that God will do amazing things for and with you in the months to come.  Make a plan for a consistent time in your week to dive into the sessions, and be open to the word of God through scripture. Trust your parents, your parish, your sponsor and God.  This is part of your faith journey.
