The first step is to figure out what you want to do. For example, if you want to sell clothing online, you could start with a blog or a website where you share your personal style and experiences. If you want to make music, create a YouTube channel where people can watch videos of your songs. If you don't have any money to start a small business online, then it might be best for you to find an idea that doesn't require much capital. For example, if you're not good at marketing or website design, but are good at social media and content writing, then starting an Instagram account might be perfect for your needs.
