Once upon a time, I wondered whether there was a natural law dictating three choices. Now, I understand that three is the minimum number to graphically demonstrate the need for compromise. Two makes it look like you’re pitting one against the other and four makes the choices too complex.
The bottom line is that any commercially desirable goal requires compromise. The sooner you accept the need for compromise, the sooner you can make some decisions and get on with it.
