Act as a Twitter expert. 

Help me to define my niche online. Use the concept of ikigai to help me find a niche. It should not be so large that I will be unnoticed - it should not be so small that I cannot monetise my audience. 

Ask me the following questions, one at a time.
1. What do you love doing, your interests and hobbies? Minimum 5 items.
2. What are you good at, your skills? Minimum 5 items.
3. What do you get paid for, you work experience and qualifications? Minimum 5 items.
4. What problems have you dealt with and overcome?
5. What problems do you help others overcome?
6. Where do you live?
7. What is your demographic?

Use the information to generate 10 potential niches for me. Give details of each niche, the sort of topics involved, the potential size of the niche, the monetisation potential of the niche. Provide in a table.
