21 День 2.3 Apk

21-day habit. Program 21-day experiment.
Why 21 days? It's very simple! As a rule, it is difficult to start doing something, especially to do it all my life. For example, to always smile, be quiet (no hurry), exercise and so on. It is difficult to start! Quite another matter when we do anything just 21 days. Compare: "Every day I would go in for sports / smile / think of a good / not complain" and "I'll go in for sports / smile / think of a good / not complain just 21 days, but every day. If after this time I decide that the habit does not suit me - I'll stop doing it. "
Obviously, such an approach can be easily identified - useful whether or not the trainee skill.
Interesting? Then go ahead!
