To improve myself, i have to learn a lot about society and the world.
About the society, i must learn the culture and tradition of anywhere.
Outside, i have to greet everyone who i meet.Use positive self-talk is important, too.
Practice random acts of kindness when you talk with everyone.
Get enough sleep to have the science course.
The most important to improve myself is win myself, it's mean you have to do everything you say, keep the promises.
These things can improve myself.

Good luck!
