He learned his workshop skills from the participants' feedback. Thiagi's approach to his work is based in his personal philosophy. Don't take yourself too seriously. Thiagi thinks that the most important skill for a performance technologist is to not rigidly believe or adhere to any one thing. There is no one simple right way to do something.
Eclecticism allows flexibility and options.
The aspect of Thiagi's philosophy that has the most impact on his work is his belief in having fun. He would like his epitaph to say that he dropped dead in the middle of a workshop while making people laugh. He views enjoyment, for both the participants and the trainer, as an important quality criterion. Enjoyment of training supports improvement in performance. Anyone who has attended a Thiagi workshop for the first time will be struck by how different it is compared to most other workshops.
