This Wayne Dyer quote reminds me of some success stories that I read in a Tony Robbins book.
The invention of the stick-it notepad was the result of a failure. The man was trying to develop a glue that would hold anything but ended up with something that hardly stuck at all for strength.
Instead of asking himself the wrong questions and getting himself into a frenzy he asked himself, “How could this be useful?”
By asking himself the right questions his brain came up with the answer. If he had asked himself, “Why am I a failure?” his brain would have came up with reasons why and that would throw him into a frenzy.
If any obstacles come your way think to yourself how can I turn this into an opportunity instead.
