In a 2003 interview, the late singer Donna Summer described being stuck when trying to write a song. Sitting at the piano, she noticed a Stephen Bishop album lying there, and asked herself how he would approach the song. Almost immediately, the line “It must have fallen out of a hole in your old brown overcoat” came to her; the result was “On the Radio,” one of her biggest hits. If you have a seemingly unsolvable problem, ask yourself how someone else would approach it – a competitor, a mentor or a famous person. It might be the key that unlocks everything.
