Now, your residual income stream should be in place and working. So, you can easily lower your work load if you done your work efficiently and the income will just come :)
If something isn't right you can jump and review the steps you made and correct any mistake till every thing is great. When every thing go smooth, go to the second step.
The second step is improving your website to the max and keep adding good content to get more traffic and conversions and when you think you hit the roof and you can't get more income from this website, build another one with different niche.
Which means you should learn other things to write about and have a good content to share. So, always try to learn new things.
I hope this was good and informative
Sorry for my English :)
Good luck my friends.
