I've recently read a book called Zero to One, and I'd like to share my takeaways from it. The author of the book is the ex-CEO of PayPal. Yes, it's Silicon Valley.  Yes, it's all about tech. So, the author knows what he is talking about. This book will be helpful for those people who want to start their own company. So, I am going to talk about the fundamental idea of the book (to my mind) and share a checklist for people to comprehend whether you should start your company right now or not.
