"Some people believe that life is happening to them, and because of this, they get weighed down when something bad happens," Tony Robbins says. "Other people believe that life is happening for them, and that each incident - good or bad - is shaping them into the person they're meant to become. Which one would you rather be? If it's the latter, it's time to change your mindset."
This doesn't make sense, and is probably misquoted. It should read "if it's the FORMER, it's time to change your mindset". The former is the negative one, the first one. "Latter" means the most recent statement, which is the positive one.
