enthusiasm is certainly important and gives us momentum in things; I believe that it happens quite often that we get lost going forward in projects (obviously not in everything, there are things that will arouse perennial enthusiasm in us heh heh).

I believe that enthusiasm is one of the things that makes the difference, in fact those who are persevering even when they lose it continue to follow the road until they reach their goals; there are others who give up instead... I believe that enthusiasm is one of the watersheds between successful people and people who are still working to become successful (success in all its meanings, given that it is still something quite subjective).

Very interesting and beautiful post!
