1. Tutor
Who said you need to have a whole teaching background to teach others something you’re good at? You can easily begin by selecting the topic on which you want to be tutored. Then you can start helping others learn and you are good to go.
Don’t forget about some little self-promotion that you will need to make yourself known to others. This will make you happy, but it will also bring you some extra cash.
A win-win situation you can’t refuse, especially if you still have some time off (if you are already retired). Keep in mind that if you want to do this on your own, you can set the timetable and the hours when you are available.
If you choose a platform to register on, your extra cash might be cut in half because you will have to pay for the hosting too. Choose wisely!
