Nobody Knows You Like Yourself.
People can be arrogant in the fact that they tend to judge a persons character within second of meeting them.
We all generalise, we form assumptions, we create an opinion of people from the first moments of the first interaction, often inaccurate ones. The truth is, despite the lightening-quick opinions people form, nobody knows you like you do. You know your own strengths, your own weaknesses, your likes and dislikes more than anybody else in the world. Yes, people can be quick to judge. Are their perceptions of you at all accurate? It’s unlikely. Don’t concern yourself with them.
