There are no original ideas anymore. Instead of trying to come up with a new idea, why not build off an existing one?
Here's some examples:
- iPhone accessories
- Mobile apps
- Fitness videos
You may be saying, "I'm not skilled in those areas," so take the last product you purchased enthusiastically and build off that.
It's much easier to tap into an existing audience versus trying to create a new concept (which probably has been done before).
Successful businesses adapt and companies such as: Amazon, Google and Apple have transformed into "platforms" because of their various offerings to the masses. Each of the offerings is considered a plank.
Ask yourself, "What companies can I be a plank for?"
Imagine the partnership opportunities. Not only do you have a shared audience, but also a context to build off of. Exposure is crucial in today's economy and you'd be foolish to go it alone.
