How do I deal with knowing that I’m not going to be good enough for some people

IV wanted to get to know this one person who super nice friendly texted me first started conversation and asked how I’m doing but I’m not really good at keeping people around or entertaining people so it’s this voice telling me that you wouldn’t be enough for them they deserve better and off course I’m not going to be able to please everyone I meet but when someone is nice to you first is something that doesn’t happen often so how do I deal with letting go of people
