My suggestion isn't quite as good as the 6 billion boars, but might take less time: You build character whenever you overcome adversity. Make an effort to improve an area of your life that you struggle in.
you can build your character by following these steps : Be careful what you say, it affects how you think; Be careful what you think, it determines what you do; Be careful what you do , it determines your character; Be careful about your character, it determines your destiny.
Building character is integral to leading a productive and enjoyable life. With strong morals and ethics, a person can make the most out of any situation, good or bad. Undergoing personal development not only benefits you, it also influences those around to you, too.
