Mukund R's Key Ideas from The Diary of a Young Girl
by Anne Frank

The best remedy for those who are afraid, lonely, or unhappy is to go outside, somewhere where they can be quite alone with the heavens, nature and God. Because only then does one feel that all is as it should be and that God wishes to see people happy, amidst the simple beauty of Nature. As long as this exists, and it certainly always will, I know that then there will always be comfort for every sorrow, whatever the circumstances may be. And I firmly believe that Nature brings solace in all troubles.

What is done cannot be undone, but one can prevent it from happening again.

I know my own faults and shortcomings better than anyone, but the difference is that I also know that I want to improve, shall improve and have already improved a great deal.

A religion, it doesn't matter which, keeps a person on the right path. It isn't fear of God but the upholding of one's own honour and conscience.

How noble and good everyone could be, if every evening before falling asleep, they were to recall to their minds the events of the whole day and consider exactly what has been good and bad.

Then, without realising it, you try to improve yourself at the start of each new day; you achieve quite a lot in the course of time. 

Anyone can do this, it costs nothing and is certainly very helpful.
