1. Know that if you do not live within the scope of today, your thoughts will be scattered, your affairs will become confused, and your worrying will increase. This is the meaning of the hadith:
“When you are in the morning, do not expect to see the evening, and when you are in the evening, do not expect to see the morning.”

2. Forget the past and all that it contained. Being absorbed in things that are gone is sheer lunacy.

3. Do not be preoccupied with the future, because the future is in the world of the unseen, do not let it bother you until it comes.

4. Do not be shaken by criticism; instead, be firm. Know that the level of people’s criticism increases in proportion to your worth.

5. Faith in Allah and good deeds are the means of a good and happy life.

6. Whoever desires peace, tranquillity, and comfort shall find it all in the remembrance of Allah.

7. One should know with certainty that everything is according to a divine decree.

8. Do not expect gratitude from anybody.

9. Train yourself to be ready and be prepared for the worst eventuality.

10. Perhaps what has happened is in your best interest (though you may not comprehend how that is so).
