You weren't baptized, you ARE baptized
Stealing something I read yesterday:
Don't think of "being baptized" as an event, think of it as a condition. Don't say, "I was baptized," say, "I am baptized."
Then live that way. Live as one who is baptized, who is dead to sin and who lives for God.
The Sacrament of Baptism doesn't give you a supernatural ticket you put in a file with your baptismal certificate, to pull out and show St. Peter after your death. It gives you supernatural powers you can and should use every day of your natural life.
