How do i get a job if im 16 with no expeience

First, you have to want to get a job.
.
Congratulations!
.
If no one else will hire you, just hire yourself!
Things I did at your age: mowed lawns in the neighborhood, babysat (You don't have to be a girl!),gathered berries from some abandoned raspberry bushes in a vacant field and sold them to neighbors, stuff like that.
Depending on where you live and your personality you might try some of these: Buy some newspapers very early in the day and then resell them on the street or on a very popular location with affluent people. Even though you will be selling them for the same price you paid I bet you will get enough in tips to make it worth your while. Try buying 20 papers and see what happens. You must do this very early in the day.
You may even be able to buy them wholesale from the local newspaper publisher. This is a variation on the old paper-route but you will be providing more service and the option for tips. If you can learn how to sell successfully you will always have an income.

If you live in a small town try going to a small service business and asking if they will pay you to do some odd jobs for a few hours for, say $5.00 per hour or so. You are not asking for a "JOB" like being on the payroll ... just to sweep out the storeroom, Windex the front windows, empty some boxes on to a shelf. something like that. Work from 1 - 5, say. Get a twenty in hand and you will check back in case they need anything else. Try at a barber shop, small retail store, etc.
Volunteer to work for FREE someplace that really interests you just to get some experience. Have a great attitude, work hard, and after a week or so you have some EXPERIENCE. They may offer to pay you something since they will feel guilty if you really do work hard and are of value to them.
"I'm really interested in the printing business and I would like to volunteer to work here helping out about four hours a day for a few weeks just to learn more and see how its works. I'm not asking for any money. I just want to learn more about the printing business."

Poochie worked at my barber shop during the summer. He has a positive attitude and is a hard worker. He got along with everyone. He is a great kid and I recommend him very highly.
