You have a plan for your gym workout. Now, imagine going there and instead of doing the work, you spend time searching for ways to cheat and avoid it, just to formally complete the reps and sets. Do you realize you'd only be deceiving yourself, making the entire workout meaningless and wasting your time?
This is what most people do with various aspects of their lives every day.
Whatever you do, always give it your best and push your limits. Otherwise, you're just wasting your potential... and your life, too.
