Doing for the sake of doing becomes a paradox when it creates extra work. Why take on more than you can handle?
Overworking is an addiction. You don’t just do it. You do it for a practical reason: a paycheck, curiosity, helping others. On the other hand, people do less when the work sucks. They cut corners and half-ass it. People lose hope when they don’t see the point in their shift.
Everything is practice. When the work sucks, the process matters even more. Whether it’s interning or playing water boy, the skills you learn will help you elsewhere. Doing is learning to connect the dots so you can get the job you actually want.
But if you do enjoy the work, avoid taking on more than you can chew unless it really matters. Doing just to do hurts more than it helps.
