I highly recommend you to watch “Touran Khanom”. It’s a documentary about Touran Mirhadi, the founder of modern education in Iran and, this documentary focused on the last years of her life; the time that she works hard while she is very old and sick. The most important her quote is: “Convert your huge sadness to a huge work”. She learned it from her mother and, she always does it.
Last day, I write something to one of my students, that instead of wasting your anger from the government by spreading jokes and junks, try to be more powerful, by improving your knowledge and your skills.
And today, I watched this documentary, I think it was an inspiration from heaven. So I highly recommend you to watch it again.
