As any job there are going to be ups and downs and clashes in personality with certain ones you work with. But I have always focused on why I am I chose this as a profession, to be there for the children, physically and emotionally.
In all I have always had fun in the workplace. Building relationships with the children, watching them grow, helping them achieve important life steps and goals. They remind you what's important in life and remind you to focus on the fun enjoyable parts of life.
