You don’t have to be a great scientist to be a good man.
You can have your flaws, but overall be a good man. That’s hard, not using the correct form of a word.
Knowing how to write properly is one way of being a good man, but not the only way.
On the other hand, you mustn’t despise the book. If you’re a nice person, yet lack some skills, don’t have a superior look at the people who know more than you. Knowledge is a form of power.
Should you read? Of course, but you should also try to be good.
“Dacă nu putem fi buni, să încercăm să fim măcar politicoşi.” ― Nicolae Steinhardt, Jurnalul fericirii
