To be an indispensable go-to person is all about saying yes to everybody and everything. In other words, you have to over-commit yourself, which means that you have to stretch yourself beyond your capacity. In such cases, the tendency is you overlook the other things and end up with jobs left undone or done ineffective, or worst, everything you do starts to fail. Surprisingly, becoming indispensable at work doesn’t work this way. You only have to be known for executing one important thing after another very well, very fast, all day long.
