If you are enthousiast to the present moment that is great , the
problem
arise when you get enthousiast for the future ( expecting certain
outcomes )
or for ideas that might not hold their promises . the result often is
a
counterreaction of blocking the source of enthousiasm . And you end up
sarcastic at the enthousiasm of others judmental and cynical.

far from me the intention of blocking your enthousiasm . I  just would
prefer  the paleoidea  not ending up under the fire like the vegan one
do
 it just doen't help understanding). IMO they have both valuable
things to
say., and an underlying common ground .
