Being soft-hearted and feeling embarrassed only drain yourself; indifference and forgetfulness are the true tools for survival. The quietest person in the crowd is often the most capable. The person with the best temper in the crowd is often the most formidable. Never expect to change others at any time; just like when it's raining, you can choose to hold an umbrella or call a taxi, but you can't fight the rain. Don't get soaked just to hold an umbrella for others; it's not that you're bad, but that you and they are not the same kind of people.
