5. Be wise in making friends

Making friends with good quality does not only elevate you, but also change the perspective people view you. Making bad friends, however, would show that you're contaminated among them even if you're not affected. 

• Be selective in choosing friends. Do no make friends out of kindness
• This is important because making friends with bad character would assimilate yourself with them. Thus, it would be difficult to distinguish right and wrong in the environment.
