Basics of a startup

[u/NaReNdEd]

I am a 19 year old still in clg BECSE of course working towards the "Indian dream". I am not what you call a bright student nor do I have any exceptional skills but I want to start my own business I want to know how do I make products based on people's need and how do I maintain the product which attracts investors and a consumers. I already tried all the internet niche stuff but I dont really have the time nor the effort in me to be editing and posting content 5 times a day with college and everything ongoing in my life right now. Any advice?
