Then find a small niche (customer base that isn't being catered to well).... and create a solution that solves a problem for them (problem of lack of money, low confidence, lack of knowledge in X area, in finding a partner/lover).
Make sure its very niche, because then you can talk directly to that audience about their exact problem, their frustrations, their goals/dreams... if they believe you understand them 100% and their problems 100%.... then they will believe that you're solution is likely to solve their problem, thus they'll buy the thing you're selling.
Niche to look out for; ones with a PAINFUL problem that is also URGENT. Someone that needs to lose 20kg because 6 months from now they're going to have a wedding would be more likely to take action than targeting someone that just wants to lose weight... for what reason - no idea, any particular time frame, nope....
Someone that needs save HIS/HER marriage or 30 days from now they'll be getting divorced is MORE likely to take action than someone that wants to just improve their relationship.... (there is no pain/urgency for the latter).
Lastly... go read about copywriting, sales and consumer psychology. Thank me later.
Good day.
