Is Your Brain Asleep on the Job?

If you don't find your job challenging, you've likely zoned out due to boredom. Boredom arises when you have maxed out, learned as much as you can learn or mastered all the skills required to perform your job, particularly if your job doesn't require complex thinking and analysis.

When it comes to your brain, the 'use it or lose it' principle applies.

 monitoring goals keeps your brain focused on the task, even while it sleeps; and if you link pleasure to achieving your goals, your brain will be even further motivated to perform. Your brain is wired to understand the good consequences that come from distinct action; setting your workday up so that it can perform to its peak capacity is a recipe for success.
