Work.

Early in my career, I made the mistake of revealing to my employers that I’m competent at my job. More and more work flowed onto my plate and before long, I was assigned tasks that were supposed to go to seniors. So, the seniors received almost double my salary while they enjoyed more open schedules since I was doing my work + some of theirs.

It’s simply not worth it to go above and beyond at work, unless it’s your own business.
