Life has purpose
What happens in yours and other peoples life do not always has a purpose, but there is purpose in life. It is a purpose that is not connected to achievement and ambition. How great you are, or not, is not what gives you value, and not what defines you.
Who is looked up to and who is looked down on, who is popular and who is a celebrity. This is just noise that makes us fear the bottom and aspire to the top. It is good to do good work, to be able to say "look, look at me, see what I was able to do"; but it is not what gives you value.
