Become a day laborer either through Craigslist, temp agencies, or social connections. The trades are desperate for help in the USA so you will likely get lots of opportunities to learn from specific tradesman. Day laborers rarely work alone and you will get the opportunity to observe different jobs in the field and decide what you want to pursue. If that doesn’t work for you search Lube Tech in the job boards you can usually pick up the entry level position with almost no experience (do you know where the oil goes? do you know what a tire is?). Once again like a day laborer you will learn by being present in the shop. If that’s not your thing pickup a cheap lawnmower or snow blower from Craigslist and push it around your neighborhood. Knock on doors, offer to cut a lawn for $20-$60. In either of these scenarios keep a good attitude, show up everyday on time, and trust me you won’t be unskilled for very long and the money will come in time.
