Absolutely, starting a business at 16 is possible, though some aspects might be more challenging due to your age. You can certainly begin with smaller ventures, such as lawn mowing or creating and selling homemade products online. While setting up a manufacturing facility may present more hurdles, your ambition and early interest in entrepreneurship are commendable. Remember, though, that being young might affect how others perceive you, especially in scenarios like securing a business loan or offering high-value services. However, with enough determination and a smart approach, you can find ways to navigate these challenges. Your ambition is key, and there’s always a solution to every obstacle. Pick up a couple books on accounting, business strategy, finance or any material that may be relevant to your objectives. Best of luck !
