But...I Can't Even Pay My Bills!
This is often a reason people give for not starting their own businesses. This is a reason to pause. If you're financially unstable because you do not manage money well, you might want to rethink your ability to run your business on your own. It will be unlikely that you will be able to run your business well either. However, if the reason for your financial struggles is the fact that you just aren't making enough to stretch the money, maybe starting a business will be the solution.
Let's face it, it's hard to put in your labor and your efforts for a company just to get minimal returns back on your time investment. It's hard to feel that zest for life when you're only getting pennies per each dollar the company makes. When you spend your time honing your knowledge of books and the publishing world, and you make a little more than minimum wage, it can be difficult to feel motivation to continue working in a corporate bookstore.
If, on the other hand, you wanted to put forward the effort to create an alternative bookstore, or a sci-fi geek bookstore or create an independent publishing house, you'd reap the rewards of your efforts. The potential for earning would be greater, because when you run a business, often times what happens is you get out of it what you put into it. If you go in with a solid business plan, spend the time necessary to build your business at a reasonable pace, and you take time to develop yourself professionally, then it's likely you will do better and make more than you would have at the stable job.
