@Em Ma I fully agree with you that we only select those niches which know more before writing copy for those niches. But I have seen many people jumping into many niches, doing deep research even if it feels overwhelming and boring but their main purpose is making money. So, they dig deep into the high profit niches and after certain period of time, they master those niches. Like me, if I say honestly, I belong to a professional life of more than 20 years in the non-profit sector. I write funding proposals for climate smart agriculture, water scarcity, poverty alleviation, livelihood improvement, donor funding etc etc. I am also good at data analysis tools, data collection, reporting and communication. But if you see, these niches have very little importance in the business life. If we take the example of DTC products, many new business are being established in the top countries, so people are more interested in these niches as they are huge and running everytime round the clock.
