Hey buddy. I understand. I didn't know your age. I take back the 'leech' part. And I know I'm a little hard. I'm sort of a hard guy in some ways. But if a guy is tryin, I'll back em up to the max. I've even gone to court to testify in various kids' behalf when they got themselves in trouble. Ended up with an extra kid that way once too.

When my boys were 13 some of the things they did to make money were:

Car washing; usually they added a buddy and of course got more water on themselves than the car being washed. But they made some money.

Dog walking; this was pretty straightforward. Just ask around neighbours and friends who have dogs.

Babysitting; while my boys didn't really like this job much, they did it from time to time when they needed money.

House painting; naturally this one will be harder to nail down as you will need to find someone needing the job done. Two of my boys did this at 13.

House sitting; One of my boys did this at 13. If you present yourself in a mature way, you might be able to do it. Mostly the people my son worked for just wanted someone there to receive packages and collect mail while they were gone to deter porch pirates, etc.

My sons also did a hella lotta yard work, but I didn't mention that because you said you sucked at it.

I also paid my sons to help me do various things. Mostly to work on motorcycles, four-wheelers and the like. Maybe a friend or relative would pay you to assist them in some project.
