Don't be armchair critic to agree to differ; don't cry for the moon but do what you ought to insist on; what should stand to reason; and prove being responsible that you have offered.

If you don't agree with something, then criticize it; if you're going to criticize it, then suggest something else; if you're going to suggest something else, then do it; if you're going to do it, then assume responsibility for it!

Criticise if you disagree, suggest if you criticise, do/act if you suggest, take responsibility if you do!

If disagree - criticize, criticizing - suggest, suggesting - perform, performing - be responsible!

You disagree - criticize;

you criticize - you suggest;

you suggest - you do;

you do - be responsible
