A person who voices faults found in every ideal. Existing does not seem a wise basis to determine if announcement is appropriate. This thief will without regard for the, for lack of a better word, feelings of others, opens his or her big mouth and shatter hope, aspiration, and dreams. I've heard it proposed there is weakness in the victims of dream thieves and a thief cannot steal from a strong individual. Even a strong person can not hold out forever.
Association helps the strong and the weak build their dreams.
Get around people that are where you want to be, who have dreams you'd like to have, and who know how to create ideas, set goals, and make a plan of action to follow through, and who do follow through. Those people will help you keep what you have from those who would molest it. What's in your head is precious material, and must be protected. It will form your future and be your guide. Do not let it be damaged, do not let it be tainted by the dark chasm of other people's ideals.
