Create A Membership Club
A membership club is a great way to earn a regular recurring income. If you have a skill, area of expertise or something you can share with a wide range of people then creating a membership club could be a perfect way of doing this.
They are great because you only have to do the work once. Then you charge people a monthly fee to access this important content or information.
It can also be product based, for example, sending out a spa bath kit every month for stressed working mothers, however, this involves more effort on your part and is less mobile.
I would recommend creating a course or training programme and then offering this to people for a monthly fee in order for them to access it. You would also want to keep updating the content to keep people interested.
