What about when you have multiple states? Is there an option better than creating multiple flag variables? The C-language has a declaration type just for this purpose. It is called an enumeration, or enum. Setting up a state machine with enum is a surprisingly simple. Arduino and embedded programmers should use them! All you need to do is create descriptive tag names, and let the compiler assign them an integer value. Unlike a #define which is just a macro replacement, the compiler treats an enum as your personal variable type.

This presents a problem when you want to flash a LED while waiting for a pushbutton to be pressed. Flashing the LED with millis() and using a flag variable to find if the LED should be flashing solves this problem. Consider this another example to my virtual millis() cookbook.
