developing a habit

I didn't read the original article sayingdeveloping a habit needs 21 consecutive days. As far as I can remember, I heard it first from my favorite radio program 3 years ago. At that times, I loved a female broadcaster more. She had been a host for 7 years until she stepped down suddenly. I am still wondering her well-being in diplomaism of Korean society. The reason of her withdrawal was a counterfeit scandal for her academic career. During the broadcasting, she always used to encourage listeners commenting that research. She emphasized waking up early just 3 weeks could make everybody early bird. I am still a big fan of that program, however, sometimes I miss her vibrant and strong voice. Her co-host has been doing his job well with a new guy until now. I have exchanged textmessages with him from time to time.
