You've got to exploit exposure to leverage and assets aren't free. The main problem with most online 'business' ideas is they claim to be cheap or free to setup and require almost no effort, time or ability to operate. With such 'barriers' to entry don't be surprised to find they don't work.
As much as we hate on capitalism if you break it down the logical rules/processes are relatively simple to understand. Drop shipping works if you identify non-shitty products/opportunities and are prepared to put in work to significantly add value.
Most business ideas are basically identify a niche, make an investment, add value to it, sell it for a profit. It helps if you can also exploit market inefficiencies while doing so.
The most basic business here is shit like window cleaning or gardening work. Even if you are a lazy piece of shit you just hire people to do the work while you oversee. You'll find people who just want to get paid and then go drink or do drugs or people who don't like to negotiate jobs or source materials, people who can't take the money for whatever reason.
Get a van or truck. Hire two people for $75 a day. Drive them somewhere and charge the homeowner $500 a day. Complain bitterly about the cost of materials, tools, insurance, gas etc and having to cover absences out of your pocket. Charge the homeowner almost full retail for materials while winking and offering a 'trade discount' on shit you buy for 80% off list.
You want to hire people who basically can't be paid until the end of the week because otherwise they'll vanish drunk. You might have to pay some of them daily to prevent them drinking themselves to death or getting in trouble.
