Follow Your Purpose
To be successful, chase your purpose rather than your passion. New studies show that purpose gives you resilience, and that's what will get you ahead. Chasing passion makes you less satisfied at work because work is often difficult and draining.
Instead of asking what makes you happy and "following your passion," ask yourself what you care deeply about. By focusing on purpose, you align your work with your deepest values and also relieve yourself of the expectation that the long slog of a career will be all (or even mostly) happiness and sunshine.
