If they find a good strategy for example:
Writing an eBook using existing tools they’ve got.
Setting up a blog using Blogger – free blogging software.
Marketing it via article marketing sites, and social media sites such as Facebook, twitter, or youtube, and finding a free payment site they can sign up to.

The can hone their skills and earn some extra cash from this which, they could then later on move into other passive income ventures like an MLM business, an Online Business etc.

However I’ve found that trying to do things for free could take a lot of time, and energy, and I don’t mind investing a reasonable sum to get tools that would work for me.

So it might be worth them getting a second or a third job to save up some money to get their passive income venture off the ground. They probably would get it started much faster… since an injection of Cash mean Leverage.
