Sadly, your skill-set is of an employee not an entrepreneur. If it was the other way around you wouldn't be asking such questions. Ideas are a dime a dozen it's execution, and follow-through that makes it happen. IF you're stuck on the idea stage, and you've been online for any amount of time with development skills there's 100000s of issues that need "fixed" you could do, not being aware of any = not an entrepreneur, in reality... The brains work a bit different
Sadly, if you can't come up with 1 or need to be told then you need to get a job working for someone.
The truth is most people want to run a business, start a website of their own, etc... very few follow through or put in the research/time/etc to do it... no one is going to be there to hold your hand the entire time. You need to be able to handle rejection, problems, etc.. and you're not off to a great start with anything.
