I always believe that the best is yet to come.
The question is not whether the thing exists, but whether it has any essence which is capable of existence without us.
All things are possible until they are proved impossible and even the impossible may only be so, as of now.
The future belongs to materials that perform exceptionally while leaving minimal environmental footprints.
The world is in a constant state of flux. Nothing remains the same from one moment to the next. You can never step into the same river twice.
