I want to start my own business but what shall i sell?

I would really like to set one up. but I really dont know what to sell and how to get some profit.
what I really want is to get lots of money via this. so when im older I will have more money stored away.
like I've heard of a 14 year old making...

millions from selling jam!!!
thankyou

dont try to start a business because it could fail and you could lose more money than you earned and if you want to be rich you just save money like dont go out to eat dont smoke pack a lunch etc this will save thousands a year

You can't make a TON of money from this very FAST, but sell stuff on craigslist. You don't have to pay them.

Right now the economy is really bad and people are not buying just anything. You have to give people what they want. When whatever you sell becomes unpopular, you have to change with the demand.
Don't be afraid to start a business based on it might fail. Its better to fail trying than not to try at all!
You just ned to plan, organize, and do your homeowrk. Check with your local SBA(Small Business Association).They can offer a lot of tips on small business start-up.
Good Luck.
