​Drop shipping niche products

I have recently thought of a business idea that I think is really good, but I would like you to hear your opinions.

My business plan is simple. First, I will create a YouTube channel to gather an audience (ideally for 2 to 3 years). Once the audience is there, I will sell related products to them from my own store. I am going to keep this vague so that my business plan doesn’t get stolen.

I will start a drop shipping store and list products from suppliers. In my niche, the products usually come from another country and there is a little barrier to be able to buy the products of that niche. With my store, it will save the customers time. The average age of those interested in this niche are teenagers and young adults and the niche has been increasing in recent years. There is competition but because I will already have an audience, I think I’ll be able to stand out and sell well.

Even with the initial audience, I plan on launching social media campaigns (posting on social media in hopes of getting more traction). Once I have enough money, I will start paying for ads and reviews.

I would like to know if you think that this business can succeed long term?
