I’ve researched how people define GPS as it relates to the human condition, and I think best-selling author Jim Samuels’ philosophy is the simplest and most effective take. Samuels’ formula involves goals, problems, and solutions. We set goals and then solve problems that arise as a result of those goals. For example, if you’re thirsty, you get a glass of water. The process is actually quite sophisticated if you try to break it down, but most of the time we handle it subconsciously.
