There has to be always an alternative plan, active -passive income is one good thing that keeps one person knowing how to survive without the first one not going well as per wishes.
What passive sources of income gives mostly to us that I admire that, you have your backups first to at least help solve 10% of the cashes you need. What if no lenders and friends to borrow you this much, then even a slight boost of needs the emergency time is vital.
I always wish people to have so, even if they can create that - a short supply of money be guaranteed any means. Thats the edge.
