I respectfully disagree. I looked at the list and for the most part I could easily connect some type of hobby that would correlate with each of these income sources.
The definition of a hobby: an activity done regularly in one’s leisure time for pleasure.
The art of turning a hobby into a business is about being creative in how they turn what they love to do into an income source.
Not knowing which specific item you are referencing, if someone enjoys doing something for fun (i.e. hobby), this list of income sources are viable.

Hi Roshan – I don’t know about that field specifically. But you can google “public speaking” and see what comes up. You might look for public speaking forums or groups and get advice there. You may also need to get a mentor if you’ve never done it before. And of course, you can always volunteer to speak at local events to help build references and a resume.

Hi Amanullah – I don’t know much about that business, but I’d recommend first checking any licensing requirements in your state or city. Then I’d check with fitness clubs to see if you can start out working there. You might also try soliciting local businesses to see if their employees are interested. It’s a strategy of building it up gradually. From there, see where it takes you.

I would like to pursue with Fitness Programme, Since I’m a fitness enthusiast.

Ranging from Daily Yoga Practices to keep your Energy Balance, to Maintaining a healthy Life style despite of working 9-5 regular job ,I could provide fitness training on varying programme.

Can I request for your advice to get started please.

Hi Abubakar – You can try art as a graphic artist. You might be able to take some courses at a local community college, or even buy a graphic arts program and learn for yourself. If you have talent for it, and master the technical side, it may be a way to turn art into in income.
