It depends on your age and location and ability. Then it depends on what you mean by "make money". If you just want a job, any job, walk down the street and go into every door. You will have a job before the afternoon runs out, but it might not be a great job. You can make a nice living selling stock options, but you need a solid education in the business. You can get a lot of money selling illegal drugs, but the stability of the business is never certain (meaning you might get busted or killed at any moment). I walked through neighborhoods knocking on doors and offering to wash windows to get money. But the job that took me into retirement was driving limos. Not taxis: limos. At least in a limo all your customers are gainfully employed and speak English.
Bottom line: you need to get specific to get a meaningful answer.
