"I had never really pictured myself working in children's ministries. I always figured I would be more comfortable with maybe teens or adult ministries"

Willie Aames' quote talks to the concept that we typically have preconceived concepts of what our lives will look like and what we will be comfortable doing. He had never ever envisioned himself working in children's ministries, and instead presumed he would be more comfy with teenagers or adult ministries. This recommends that he had a certain expectation of himself and his capabilities, and that he was amazed to find himself in a different function than he had actually thought of. It also talks to the concept that we can frequently shock ourselves with our own abilities and interests, and that we must be open to exploring new opportunities and functions. Willie's quote is a suggestion that we need to be open to new experiences and that we need to not restrict ourselves to what we believe we are capable of.
