Starting a business is a big risk. You need to know what your strengths and weaknesses are going in so you can reduce the chance of failure.  In your current job, what are your strengths? Are you a behind-the-scenes type, making things work from behind a computer desk? Or are you out on the field, making connections and networking with others?  What do you genuinely enjoy about your current job? People tend to be more successful in jobs they truly love. Do you love attending conferences? Running meetings? Are the sort of person suited for a leadership position? If so, starting your own business may be a good plan for you.  Ask co-workers and colleagues to give an honest assessment of you. It can be hard to self judge so ask someone you trust what they think your best qualities as a worker are. This can help you see what role you can play in your own company and what roles you should assign to others. Are you looking for a side business, something to do for fun and make a little extra money? Or are you looking for something that could potentially replace your current job? Starting your own business, regardless of the size, is a huge commitment and carries a lot of risk. Spend some time assessing how much of yourself you'll willing to put into this new endeavor. If you don't have experience with running a business, consider getting educated. Even if you already have a degree, taking extra classes or pursuing some kind of supplementary training can help.  Consider going back to school for something like an associate's degree in business, marketing, or managing. Associate's degrees tend to be only two years and the course load may be less strenuous. If you can't commit to getting another degree, consider taking a few business classes at a local college. There are also courses in business and start up companies offered online, which can be convenient if you have existing obligations.
Assess your personality. Decide how much of a commitment you want to make. Look into education.
