Just cause you can't get a regular job doesn't mean you can't earn money.
Walk around your neighborhood. Look for homes with dirty cars, yards that need trimming, lawns that need mowing, etc.
Then knock on their door and say something like, "Excuse me ma'am, I noticed your lawn needs mowing and plants need trimming. I know you're probably too busy to do that stuff, so I'd like to do it for you, for X dollars."
Ask them to buy or supply any equipment or supplies you need and then pay you for labor, or if you have the equipment, just use your own.
I bet if you do this, you'll find lots of folks too lazy or busy to do it themselves and who would be happy to pay you to do it.
Estimate how long it will take you, plus add up what your time is worth per hour, then pad that a little and make an offer. Think to yourself, Hmmm...it'll take me 4 hours to do that yard work and I want $10 an hour, so offer to do it for $60 in case you estimated too low.
"Fast and easy without a job." Time to stop reading fairy tales and get some non-fiction books. As much as you don't want to face reality you're going to have to wait until you're old enough and get a job like everyone else.
Beg your grandparents.
