Success consists of going from failure to failure without loss of enthusiasm.
— Winston Churchill

As many aphorisms, what I find interesting here are the thoughts that it could trigger, and of all the possibilities I’d like to focus on the “why?”.
My answer, today, is that the ability to go through failures without losing enthusiasm starts from a passion, or some form of inner fire. If that’s missing, then every failure is going to be a huge blow able to stop you. If you have passion, than it’s going to be a huge blow able to make you stronger.
