Before anyone roasts me, let me address the elephant in the room: yes I am a serial-failed entrepreneur.  Bitter?  Maybe, you'd be the judge.When I was very young I had 1 successful company. Then I put my entrepreneurship dreams on hold because I went out there to get all the things that I was told I needed (work experience and MBA), my fault, I know that now.After that I have started too many companies, well . . . to re-state it properly, I have "tried" to start quite a few companies, they all failed, most failed to actually launch. My post-mortem analisis leads to common threads:- Not enough grit- My Depression &  Anxiety lead to procrastination/perfectionism, and other bullshit excuses- Too shy/insecure to market properlyAt the same time I have worked for a handful of startups, leads by successful entrepreneurs (consequently I did OK financially, OK enough as an employee) and one thing I have now realized is that there's 1 quality that is necessary to be a successful entrepreneur:SOCIAL INTELLIGENCE: the ability to sell the dream to early employees, co-founders, early investors, late state investors and - more importantly - early customers and custoers in general.I have witnessed first hand this type of selling that to me, with my faults and overly realistic/caution, was lies/deceits/bullshit but . . . even when things didn't go as promised; the recepients of those lies defended the entrepreneur (cognitive dissonance?).Part of me says that that is typical behavior of a sociopath, and these entrepreneurs with whom I had first hard, direct, insider's experience (I was an executive reporting to them) we exhibiting textbook cases of sociopath/narcissist behaviors; or maybe I am misreading it all, and they were just optimists, selling the dream, the perfect MO of startup entrepreneurs?Now that I have addressed my Depression &  Anxiety, how do I learn this type of optimism? Where can I read about it AND how do I practice it?
