Personal information on internet

I try to give only my name and last name in social media, because isn't safe for my person nor my identify in any website to know more information about me. My favorite social media is Instagram, I enjoy talking with my friends and people very close to me, also, I like to post photos in my profile and stories, especially, in close friends, that is my comfort zone. I think my limit is in public profile and stories, also the people can follow me, I don't try to post photos of my personal life or my specific location, nor i accept requests to unknown persons, I don't know what they can do with my personal information. However, I lost my limit when I travel to any place, or I go out with important people to me, because i love to post moments that i would like the people to see in their Instagram.
