My dear,
He who would learn to fly one day must learn to stand and walk and run and climb and dance; one cannot fly into flying.
By this I mean that whether you aim high or not, you must go through the steps and milestones one at a time. You cannot just do something great. Start small and build up.
All great deeds are built on smaller deeds done well.
Falsely yours,
Friedrich Wilhelm Nietzsche
