Ideas are nothing, execution is everything.
Belling the Cat is a fable first recored in the 12th ceuntry. A group of mice debate plans to neutralise the threat of a marauding cat. One of them has an idea of placing a bell around its neck, so that they will be warned of its approach. The others applaud the plan, until one mouse asks who will volunteer to place the bell on the cat. All of them make excuses!
Another way to look at it is to agree to perform, an impossibly difficult task. The mice did not agree who was to bell the cat because it is life threateningly difficult. So perhaps don't only consider the outcome when making plans; the plan itself must be achievable or it is useless.
