Twyla Tharp discusses collaboration as a practice that is essential for success. She defines collaboration as people working together, sometimes by choice and sometimes not, to accomplish more than individuals could alone. Tharp argues that collaboration has become increasingly important in the modern world due to factors like the internet and a shift in values. While challenging, collaboration guarantees change and forces people to accommodate others' differences. Tharp emphasizes that collaboration requires commitment from all parties and establishing routines and disciplines together. She also stresses the importance of preparation, respecting others, and adapting to change for successful collaboration over time.
