This summary has struck me. I couldn't agree more about what it says and requires. Every day founders have to face the doubt inherent in what they are trying to accomplish. But I think the hurdles are as much internal as they are external and the summary applies to both. Founders have to overcome the internal issues by being relentlessly resourceful as well as the external. "Why am I doing this?" is a question every founder is asking themselves daily because we are all sacrificing something to start our product. Getting over the internal hurdles requires a great deal of resourcefulness merely to justify continuing the pursuit another day. "Should I quit now? Have I done everything I can to make this work?" "I can't quit yet because I haven't tried X." You have to be resourceful to prove to yourself that you shouldn't quit just yet. Relentless resourcefulness applies to internal factors as much as it does external factors because you have to be resourceful enough to provide yourself the impetus to continue, to keep sacrificing. "I can't quit this thing because I know there is a possibility that something I'm not thinking of will make it work. I have to find that thing."
