The best advice I have ever received was around one year ago, when a good friend told me about (and pushed me to embrace) Rejection Therapy. Few minutes ago I received the best news I have ever received – a life changing phone call.
Rejection Therapy is a marvelous idea. Put simply, it is the concept that if you are not being consistently rejected/denied, then you are not consistently aiming for big things, and therefore not consistently evolving or learning. Practitioners of this exercise should find themselves comfortable out of their element and always surprised of how much they can achieve only by asking or trying. Or as the Arabic Bedouin proverb goes: اللي ما يطلع القنص ما يصيد.
Do it today. Plan for experiments immediately.
