Just stop for a moment and consider how you would answer if someone asked you: “What do you enjoy doing?”
Now think how much better that reply sounds than what you normally say when someone asks you: “What do you do?”
In formal business networking situations your reply to that ubiquitous question may be one of your prepared and rehearsed ‘elevator pitches’. You would choose the one that will resonate best with the person asking the question. (It helps to find out about them first!)
In more social situations the same question can be answered very differently. The question is often being used as a variation on the ‘how are you?’ question everyone asks without expecting a reply containing any form of detailed medical information.
You will STAND OUT, positively, if your reply to standard questions like this is more interesting and distinct from everyone else. One easy way to do this is to imagine a slightly different question has been asked. eg: “What do you enjoy doing?”
You can also ensure you STAND OUT by asking more interesting and distinct questions to other people – even in social situations. Instead of asking “what do you do?” when you meet a stranger, consider instead asking them “So what do you enjoy doing?” If they enjoy their job they may choose to talk about that, and, if not, you have invited them to talk about something else they find more fun and worth talking about. Answers to this question can also lead to more interesting conversations.
