"Health column" more than 21 days of repetition will form a habit, 90 days of repetition will form a stable habit

Psychological studies have shown that the repetition of more than 21 days will form a habit, and a 90-day repetition will form a stable habit. That is, the same action, repeated 21 days will become habitual action;

Similarly, any idea that repeats for 21 days, or repeats 21 times, becomes a habitual idea.

Therefore, if a concept is verified by others or by yourself more than 21 times, it must have become your belief.

The formation of habit is roughly divided into three stages. 

First stage:about 1-7 days. This stage is characterized by "deliberate, unnatural". You need to be very deliberately reminded of your changes, and you will feel a bit unnatural and uncomfortable. The 

second stage:about 7-21 days. Do not abandon the first phase of the effort, continue to repeat, into the second phase. The characteristics of this stage are: "Deliberate, natural".

You already feel more natural, more comfortable, but do not notice, you will return to the past. Therefore, you also need to deliberately remind yourself to change. The 

third stage:about 21-90 days. This stage is characterized by "casual, natural", in fact, this is the habit. This stage is known as the "habitual period of stability".

Once in this stage, a person has completed self-improvement, the habit has become an integral part of his life, it will naturally continue to "serve" people. Be 

a successful person with a plan and make a plan to build a good habit for yourself. Of course, because the corresponding bad habits are already very stubborn, so in order to form some good habits,

You may need to spend more effort at the same time to overcome bad habits.

       China has a sentence adage: leopards. The meaning of this sentence has two layers: human nature is difficult to change;

                  Human nature is difficult to change, but it is not a change, just a bit difficult.
