self comparison with others

 i often find myself looking at some people, who, just seem to have such interesting lives. such attractive bodies and appearances. such profound and cool thoughts, ideas, projects and creations. so creative, so focused, so interesting, so much better, so much ahead of me

now, im aware that i shouldnt compare myself with them. where its better that i compare myself to myself in the past. though, i can find myself doing it, and its much hard to resist.

i know its pointless. though , i just

i dont know

envy. hopelessness. frustration. self loathe

why? why do i keep feeling these things? 

i feel i should accept that i can never feel satisfed with myself. (what i create, what i pursue, what i experience, who i am, etc)
