So much is written about happiness at work — yet judging from Gallup statistics that show 85% of employees aren’t engaged, few know how to attain it. Given that the average person spends 90,000 hours at work in a lifetime, it’s important to figure out how to feel better about the time you spend earning a living. Here’s the catch, though: If you set happiness as your primary goal, you can end up feeling the opposite. This is because happiness (like all emotions) is a fleeting state, not a permanent one. An alternative solution is to make meaning your vocational goal.
