Why do so many people call me smart but I’ve never thought this of myself?

I am quite the goof ball and have many “blonde moments” and I’ve tried to cover these things but it’s just my personality and it actually draws people to me because I am genuine. However I have heard from many people that they think I am smart, or nice and I’ve never really thought so. I didn’t do well in school, I didn’t attend college. Do people call me smart and I’ve heard that I have an old soul, I am wise, I do speak well but I’ve never really thought much of the compliments I just go on with my life. But sometimes I do wonder why I don’t see myself that way and others do ( even if they barely have been around me)
