How do I deal with being boring?

Like really. I am not interesting at all and I think I can’t realistically change my personality. I don’t even have any good skills to show case. Prof told me to write 5 positives about me but there’s isn’t anything I can do, except for singing which I used to be good when I was a kid .I feel like even the to the people I am close to are sometimes irritated by me. I felt this experience with friends and family cousins.
