You can not last for a long time if all you want from blogging to make money from. There must be something else that might keep you going, especially in the early days when only 5-0 people to visit your blog. For me, some of the things I like about blogging are the following:
1. I love reading, reading and reading, and blogging helps me take down notes on important things I wanted to remember from my lectures.
2. I want to explore and new things, including new tools and gadgets to explore.
3. I want to be able to reach out to people and help them in ways I could.
4. I want to be able to keep track of my progress, whether technical skills or spiritual teachings, by browsing through my blog.
