Ignore the remarks that practicing calligraphy will make you introverted. Those are all lies.
Words are born from the heart. When practicing calligraphy, calligraphy can well reflect your character. The style of writing may be introverted or formal, both of which are their own styles.
Then, the heart turns with the word. If you practice calligraphy more, your mind will be different, for things and people. Exercise your temperament, calm down and think, be manly and be upright. Then you can freehand brushwork like Chinese characters.
Therefore, it is very good to suggest that you start from Tang Kai. Learning the right font is also suitable for your personality. Then, you can try running script or even cursive script. Since I don't want to be introverted, cursive script should be as casual as possible, such as flowing water and not sticking to one pattern. It may not make you extroverted, but it will definitely make you open-minded.
