You can't turn to a supervisor or co-worker and ask for help. Therefore, it is very important that you are a self-starter that can critique and provide feedback regarding your own work. Without the ability to take risk, you won't go very far with your homebased venture. There are no guarantees that your business will succeed. If you want the security of a guaranteed income, stay as an employee of another company.
Most people associate the entrepreneurial spirit with the ability to innovate.
Entrepreneurs are willing to try something new, to look at things differently, to find a niche and fill the void. Just because you work for yourself doesn't mean you can work less. Many times it means working longer hours and wearing more different hats than you did working for someone else. You're going to need the necessary experience in the field of business you choose to start as well as a background in general business basics. There are a great many entrepreneurs that have great ideas and a lot of talent, but don't know the first thing about running a business.
