It depends on what you want to do. Where im from Blue Collar jobs (construction, fabrication, oil rigs, plants, etc) are very well paying jobs and they only require a high school diploma, however, they aren't easy jobs and reequire alot of blood, sweat, and tears to say the least. You can get by without a college degree but either the work is alot harder or you have to put more time and effort into advancing in a company instead of just landing a higher paying job from the beginning.
Try applying at a call center. One of the better ways is through a temp agency. If you do well in your job, you have a good chance to get hired permanantly. A phone job isn't for everyone but the pay is great. Working with a temp agency is also a good way to get a job with the City or State, both of which norammly have jobs you can apply for without a diploma.
There are many jobs you can obtain with a high school diploma, as listed above. Most of them don't pay good until you get a raise or get promoted. With hard times in economy, the owners of businesses are picking people with degrees instead of people who only have a HS diploma or a GED. Going to college is your best bet for a respectable, and well payed job.
A receptionist? If you consider waitering a decent job you could get that. You could in rare circumstances build yourself up to a manager of some place, but most enterprises these days requires you to at least have a tertiary education.
resteraunts, construction, postal worker, bartenter,the army, ummm cant think of any more. receptionist usually wants a high svhool diploma i think. i got a receptionist job without one tho. lucky :)
In the U.S. if you want to get a good job you'll have to go to college. the great thing is with loans you can afford it and you'll pay them back eventually.
Put in applications to all kinds of jobs in your town. If no one calls, do it again within a week to a month.
Entrepreneur? If you have your own business than nobody will be checking your education level.
i said decent not overly good
