It's OK to have someone to look up to and have an example to follow, but why do you need to have an idol?
You may ask yourself, what would X do and why, and that could help you clarify your own views.
If you believe it, then it helps model other areas of life in a way that undoubtably supports the outcome.
For example, not part of Mr Buffets persona (and I believe it!) is staying up until 2am getting wasted and having 5 baby mommas.
And so anyone trying to have even a shadow of Mr. buffets success should probably also avoid doing so, and perhaps do some of what Mr. buffet does instead. Like reading the financial papers.
To give one example.
You can't get much beyond the median if you copy other people, unless you're really lucky. But if you handicap yourself constantly too, good luck even hitting the median.
