If they can do it, so can you - if you do the same things they did in the same way.
Sound advice for sure - no point in re-inventing the wheel, taking risks, wasting time.
But how far do we go in "cloning" ourselves around the model of another? We are all unique, and there are limitless variables that can influence the results of our actions, even if we are following someone else's patterns.
Better I think, to model yourself on yourself... on your ideal of yourself. You can never be sure of your limitations or capabilities until you put them to the test - and therein lies the true adventure of being you. And no-0ne is better suited to creating a better you, than yourself.
Aim to be the best that you can be - and in doing so, you'll set an example to others... maybe even become their rolemodel.
