It depends very much on two things, as the late creativity maestro Dr Edward de Bono put it:

1) What do you choose to see?

2) Where do you direct your attention?

He added these astute observations:

"The reasons that many opportunities pass us by is a perceptual one - we do not recognise an opportunity for what it is. An opportunity exists only when we see it." ...

"Everyone is surrounded by opportunities. But they only exist once they have been seen. And they will only be seen if they are looked for."

Godspeed!
