In the past few months i've become increasingly aware that many successful people around me completely full of shit. They manage to get millions in investor capital or run financially successful businesses for years with horrible ideas and business practices. (selling coffee on the blockchain, changing business direction so often engineers can't finish their projects). I'm trying to use this to build enough confidence for me to start my business ideas and pitch to investors. If these idiots can do it, why can't I?
