Doers and Commentators

While some people are busy doing things, others make excuses for not doing them and explain what's wrong with what the others do, even if it takes more time or energy to complain than actually do the job. Doers and whiners. But not all non-doers are negative. There are positive talkers, who give ideas for others to implement. They don't implement their own ideas either because they [think they] can't, are afraid of failing, find it hard to make the first step or are plain lazy.

Some professional pairs have an inherent doer vs. commentator nature, like politicians and journalists, sportsmen and fans (OK, this is not a profession), or playwrights and theater critics. But not all is black and white. Some politicians don't do much themselves, but criticize the rival party. Some journalists write articles and books presenting their own ideas. Sportsmen may criticize their spouse's cooking while avoiding the kitchen, sports fans may be good at planning family trips, playwrights may be wine connoisseurs and theater critics may be good gardeners.

While in general we are either doers or commentators, in different cases we may act as either one or the other type. I'm not saying which one you should be, just advising to choose your side consciously.
