Please help me

A classic sign of freshers, only a student or fresher can ask these kinds of questions. Nothing wrong with that, it just looks naive.

New ideas don't come as you think, you need to pick a pain point of some customer base and your idea should help them. Even more important, they should be ready to pay for it.

Whatever your plan is, experience it firsthand ask customers for the same. People generally don't know what they want so they can't figure out most of the time what improvement they need, so sometimes you need to create the need of what you feel might improve by your startup, just like pre myntra era we use to think clothes always should be bought on the stores not online since we can't feel the clothes online and other issues, but they created the need for it and now they have descent customer base I would say. There are many example, but in the end what matters is your passion and how you think about your idea, just try to be in customer's shoes and you will figure out most of the part.
