4. Personal Assistant
Progress cannot be stopped. Things are constantly changing and improving. People keep inventing new things to make their life easier. The faster we live, the more assistance we need. If you are retired, think of those who still have to go to work every day. They probably have homes, families and children and many other errands. You have such people around. Ask if they need your help. No doubt they will be happy to let you pick up their laundry, clean the house, do shopping or gardening. They will be glad there is someone who can do their routine for a reasonable amount of money. Once you prove you are a responsible and trustworthy person, you will be allowed to look after their children or help them do their homework for even better money.
