You can’t. You can only be yourself. But the fact that you admire him suggests you share some of the same values. The only difference is that he is living them.
So get clear on what it is you admire about him, and know that you admire it because it is in you also. Then ask yourself, If I truly lived this value in my life, what would I be doing – in my life, in my context? And do it.
You might also ask him what difficulties he has experienced doing the things he does. It’s sure not to be an easy path. And recognise that these are difficulties you too must overcome.
