Inspiring individuals is a calling for Darrel. Being in sales for over 25 years he has continued to feed his mind with personal development until it just became a part of who he is. Darrel uses his years of reading, listening, and continually absorbing personal development to inspire and motivate his audience. More recently he's spent time diving into positive psychology, with its research into brain science.
Combine all this together, throw in an occasional fishing analogy, and you've got Darrel's own authentic brand of personal development that allows audiences to transform themselves to be more productive and more successful.
