When you look at someone successful, you think "wow, that person is amazing, look how great they are!" But do you think they feel that way about themselves? Idolisation is something you can do to someone else, but, unless you have very severe narcissism, not to yourself.
So, much the same way you can't write a book that gives you the feeling of reading a book, or create a product that gives you the feeling of using a product, you won't ever feel about yourself the way you feel about the people you look up to. You're getting the process confused with the output.
There is one exception, which is that if you surround yourself with people who idolise you, you can see it a bit reflected in their eyes. Most of the people who do this don't seem very happy, though. Probably best to just give up on ever feeling like you've made it and instead learn to enjoy the endless process of getting there.
