Are you willing and able to devote 110% of your passion and effort to your startup?
Is staying up at night to worry about logistics and money and advertising and hiring something you can live with?
Would you be able to survive on a diet of frozen meals, coffee, and ramen noodles for months on end?
Are you willing to lose friends and family because they don't see you for weeks at a time? And when they do see you all you can talk about is your business.
Would you do whatever it takes to be your own boss so that you don't have to answer to anyone else (except your customers, of course)?
Do you have something that you are passionate enough about that you are willing to pursue it at all costs?
Are you ready to get started right now?
If you answered yes to most or all of these questions, great. But what really matters are your actions.
