Smart people are ready to broaden their experience
Wisdom lies in the never-ending process of learning something new. The more you learn, the smarter you are. You can prefer self-education. Some might feel they need professionals to show them the right way. Whichever way of learning you choose depends on you. Keep yourself updated and find out what’s going on around. Get at least a general idea of the current events, politics, literature and other essential spheres. Watch documentaries on medicine, foreign cultures and cuisines.
Smart people avoid risky moments
If your IQ is high enough, you will never take unnecessary risks. You know how much damage it can do to you and your life. Avoid risky moments if they carry dangers. Calculated people are not boring. And they are not cowards at all. They simply think well before stepping forward.
