Ridiculous......Remarkable
If someone called your plan ridiculous, read this note from Seth Godin - and see if you can turn the tables, and make the naysayers turn back to you and call it remarkable! Gutsy, Daring, Outlier, Maverick, 'Different', unique - all might have different connotations - but given this definition, probably, all of them have similar undertones. Do you have something ridiculous in mind? Remarkable - just go ahead and do it.
