John Krasinski is another actor who had a crisis of head versus heart in their formative years. Although all the signs of his youth pointed to someone destined to succeed in the performing arts - he was in a stage performance of 'Annie' when he was still in the sixth grade - he almost gave it all up for a career in teaching. Despite meeting and working with future 'The Office' co-star B. J. Novak while still in high school and being accepted to study theater arts at Brown University, Krasinski had a crisis of confidence and went to teach English as a foreign language in Costa Rica.
Despite the beautiful location, Krasinski quickly realized that he should have stayed in acting. Returning after one semester, he picked things back up at Brown and graduated as a playwright with honors. From there he moved on to the National Theater Institute in Connecticut, and the rest is history.
