When you decide to start a business, often times, you'll be doing lots of things you don't really want to be doing for that business. Like filing paperwork with the state or making sure your taxes are done on time. This stuff adds up and there is a lot of it.
To start a business, you really have to enjoy the product you are building enough to cover the work you don't want to do and enough to no longer do some things you enjoy doing in your life, as you may no longer have time for it.
Starting a real business is a challenge. I would suggest, if you do have an idea, try to build it. If you can build the idea, you might want to consider starting a business around it.
