What makes you remarkable?

We meet someone new (e.g. new colleagues, customers, other parents) most days but how these people remember you? Do you have anything that makes you remarkable or memorable? If not, you are just another person they meet, greet and forget. You don't want to tout yourself or coming on too strong. So how do you make these first introductions meaningful? You need to have a remarkable story (unique selling point, elevator pitch) for yourself and that is NOT your job title or description. It also shouldn't be something average or fuzzy, like I'm the main contact person for Project Management related questions. This doesn't mean anything to most people so they probably will forget it quickly. You want to show what you are really great at and what your are passionate about. Think about how you remember people. What get's you interested? Can you put in some time and effort to do something similar for yourself? When you do it use humility and not arrogance and expect that even the best approach doesn't always work.
