Because I love singing and praising my Lord, I volunteer with a group that does 'hymnsing' at various nursing homes.
Because I used to do street ministry and now feel the need to work from my home, I blog and do devotionals for my churches bulletins.
To earn extra income for my hobbies, I have website article blogs that have associated ads to earn provided someone buys.
To host the article blogs, I found it more economical to become a web hosting and domain name reseller than pay some provider to do what I do.
