"You have nothing to lose. If you quit your job and start your own company, and fail, you'll be much better off than if you hadn't. If you go look for a new job, you will have run your own company. Would an employer rather hire someone who hasn't run their own company, or someone who has?"

Running your own company definitely brings with it valuable lessons. If I were to get a job today, I would have a completely new perspective on the concerns of my superiors, and what really matters in a company's day-to-day operations. Before working for myself, I didn't feel any motivation at my job because I often felt I could make better decisions than my superiors. If it came down to me needing to get a job, I would clearly know whether this was really true or not.
