Obstacles are opportunities
From the latest The Suicide Squad movie written and directed by James Gunn, one of the main characters Rick Flag wears a T-Shirt with this quote on it.
According to Gunn he follows this philosophy to overcome problems he has had in the past, one of course being his firing from Marvel Studios (he since has returned). His mantra has grown on me and I think it is a nice way of looking at problems you might face. It reminded me of a great manager I had, who always said: “You can come to me with any problem, but only if you have also thought about possible solutions.”
