How Can a Person be More Sophisticated.

I would suggest to be more “learned”, study and read for pleasure, be entertained less.

Be not weakened by society or by temptation, and rather be different from the rest and even though they may be disappointed that you did not partake in their mindless entertainments and mindless activities, they will also secretly admire the person who does not give in, but instead stands his or her ground, and denies themselves pointless activities and prefers to be a person of knowledge, responsible, someone who will be liked because he or she can be trusted, liked and people really do like to have such people around them.
You see, when you are not like the crowd, the crowd knows that something is going on and they may not understand you or why you are as you are, but they will all wish that they were you, and they will wish that their children are like you.
The sophisticated person is a mystery to many, yet well respected, liked, even honoured as the better person in the bunch with wisdom, knowledge, kindness and reliable, and a fun soul.

All the best from James Martin Sandbrook.
