The FOMO effect is vague, but can cause very observable effects. If you pay attention, you can see these effects happening all day and everywhere. The FOMO effect, for example, can cause you to stop work to answer irrelevant or unimportant calls or emails. Moreover, you also constantly check your phone and don't concentrate on working because you are afraid you will miss a call or text. This will make it difficult for you to do the job well.
