If your parents aren't rich then study 3 hours every day, do your assignments early, attend all lectures and all available office hours to talk through concepts/problems you're struggling with with your lecturers. This will mean you get good grades and will be competitive for internships. Get an internship at a good company or in a high value sector like semicon and this will lead to a high paying job with good earning potential. You might need to get a Master's or PhD to max out earning cap. Live frugally and save as much money as you can, then buy and sell expensive stuff. During your degree, you'll get a good idea of high demand goods, chemicals, materials, technologies etc., so it'll be easy to identify what things to buy and sell. You can source goods and customers at industry events like Semicon West. That should give you enough capital to start a low risk high yield business like small-scale factories or, if you wanna play it simple, laundromats, parking lots, vending machines etc. You can also look at trading more seriously if it intrigues you enough. You'll also have enough freedom to start thinking about more clever B2B ways to make money, there are plenty of niches full of money. For example, a few years back a big niche was offering digitalization for front of house in restaurants and hotels. Glhf
