Jesus Sosa made a deliberate, specific choice to write his blog in English rather than his native language, treating the fear of making mistakes in a second language as exactly the kind of fear worth confronting rather than avoiding, a small but real act of courage running underneath the more conventional motivational posts.
A post reprinting a chapter from Anthony Robbins' book on the vocabulary of success argues that words carry real power to build or destroy, illustrated with a business meeting Robbins describes where a careless phrase nearly cost a deal. The five tips post recommends building a picture board of specific desired outcomes, a car, a house, a destination, and getting genuinely angry about your current situation as fuel for changing it, more visceral than most goal setting advice.
None of the three posts describes a specific result Sosa achieved himself, staying in the register of borrowed motivational material and personal intention rather than case study.
The Making Mistakes post gives the clearest sense of the actual person writing this blog.
