Hello Mr. Garcia, as an entrepreneur, what are some of the biggest challenges you've experienced, and how did you overcome them?

They fall into two categories, one is financial and the emotional.  Financially I had to save enough and get myself into a position that I could take on more career risk without destroying my potential to earn a living with the skills I spent time developing.  As I explained in another Q&A, this is the time it takes to accumulate enough personal savings that my affordable loss is enough that I could pursue higher risk ventures and if they failed it would not be a personal catastrophe.  The second aspect is one of having an emotional constitution, this is very hard to develop and takes a lot of experience, this is when all the cognitive biases impact one's perceptions such that it is hard to make sound business decisions.  I describe this in my book "Startup SOAR Coaching", see the section on cognitive biases.  For example, perpetual self-doubt and second guessing every decision, or being over-confident that some action is going get a reward.  These all get amplified as an entrepreneur and it is not enough to be aware of them, it take a lot of time to be able to control these factors in oneself.  It is way having a coach or mentor can accelerate the companies progress and avoid the mistakes that often have to do with the people not recognizing their own biases.
