Second Income

I have been working as a Salesforce developer for the past 4 years. I always wanted to have a side hustle and have a second Income. If anyone knows a genuine way to make money outside IT, please help me out. Please don't share any YouTube videos I need honest answers, YouTube the biggest scam, the person explaining about the side hustles just are trying to sell their courses nothing else. I have tried all of them but none of them work.
