The ego is the driver making the decisions. It decides between the devil (the id) and the angel (the super-ego) on either shoulder (yes, all those cartoons you've ever seen are partly true). We have voices in our mind, and it's up to the ego to decide which one to fulfill. Its goal is to satisfy the id in some way while also attending to the super-ego.
Babysitting isn’t just for teens. Everyone from college students to recent retirees can make money watching other people’s children. Word-of-mouth referrals from friends and family are still a great way to get started, but you can also create a profile on Care.com or Sittercity to expand your reach. Note any specialized skills, such as CPR certifications or experience with special needs children, to make yourself more marketable.
