What I think about TED "Try something new for 30 days"

I would like to write about a talk of TED "Try something new for 30 days" by Matt Cutts.

After becoming an adult and graduating from college, most people certainly tend to think of themselves as nothing but a worker.  I belong to a trade company. I'm a manager and salesman in Japan.  I am able to eat food and live a decent life with my family.  I actually kind of enjoy my life.  So one day in the past, I stopped thinking about other possibilities. Actually, I did so many years ago.  Although, right now I can agree with this speech.  Also, I guess that if I really want something badly enough, I could do anything for 30 days.  Additionally, if I continue to make a lot of effort for longer periods of time, I could change myself like a growing teenager.
