how do you deal with inferiority complex in corporate world?

i have strong inferiority complex and i honestly dont know how to cope with it. yes, i can always improve myself, but at times its impossible to do so when others are already so ahead of you. this has affected my relationships(friends and dating) so much. i just feel this heavy baggage on me. i can barely talk to my sibling bc of this exact reason. i wonder if there is any way to get over it
