The act of devoting all of one’s energy, effort, and abilities to a certain task.
Doing household chores for my neighbor from cutting the grass to taking her trash cans to and from the curb. She recently had knee surgery. I come over and put her air conditioners in every summer. I always make sure she has a path every winter to both doors. She's a talker but I love to know she's doing ok and she's a Browns fan like myself.
