i always remember the people of third category as that is more important its better to recognize people who may put you in difficult situations. :laugh:
Good advice. But my advice is- forget all. Be helpful to all- whether anyone helped you or not. Forget even those who left you in difficulty. They enable you to be self reliant. Forget those who put you in difficult times. They really gave you strength and test.
Rely on self. The person closes to you for the time being alone is relevant. Whether someone helped, put you in difficulty or left you in distress- is of no relevance if now at distance. .
All the three quotes are true but most of the people remember the last two without fail as they are the trouble creators. It is human nature to not forget trouble creators. :)
