I’m assuming you introspect a lot. And I’m sure you have your own measure to conclude yourself ‘average at work’.
Here’s my take on this. Try to be different & smarter at work. Don’t do same things that others do. Get into a state where you are not there to prove anything. Set your own goals at work to solve problems at work. That doesn’t mean you can skip doing hard work, but this will make hard-work fun.
Work life might seem like a rat race when you subscribe to it. The real winner is not even running this race, yet working hard at their own will.
