The benefits of painting:

1, enriching personal life. It lets you learn to deal with a person's life. With painting, you are no longer lonely. When you have nothing to do, pick up a pen and concentrate. A painting lasts for an hour or two. Not only can I not spend time, but I can also get strange satisfaction from it.

2. Make you more confident. A person who can draw seems to have a skill. No matter in school, training class or collective environment, as long as you have the opportunity to draw, you will find that you have your own advantages. So you will be more confident. Because it's a technology. Not a bubble.

3. Have a deeper understanding of things. When you start painting, it is inevitable to understand the inner feelings of a character, the effect of an environment and the artistic conception. And some combinations of effects. From this, you will understand people's thinking better and understand the reasons for some artistic effects. And these reasons can make you feel life better.
