Focus is the ability to give undivided attention to a process. Parenting is a task that requires high focus, which is why everyone who will be involved in it is advised not to be lured or pushed into it accidentally, by circumstance, or for any selfish purpose. Parenting must be a choice made deliberately because of its consuming nature.
