Who is this everyone? If they are your MBA batchmates, they don't know sh*t. If they are the "wisdom activators" on social, they have not even lived a single lifetime of their own to be able to impart wisdom on how to excel in life.
Be your own person. Diversity is the cornerstone of human progress. If everyone thought and behaved in the same way we would never have had any scientific and artistic breakthroughs and would our textbooks would still say that the Sun is the center of the universe. If everyone was outspoken, we would still be fighting over words.
Read up, form your own opinions, be open-minded, be humble, always look for different sides of a story and don't just believe a single point of view.
If you are an introvert (just like me): you will still excel and get by. You don't need to network with 1000s of people. Read Quiet by Susan Cain.
