Doers and Deciders
Some people are deciders, they like to argue about how things should be done and why. They don't want to actually do the thing, they just want to sound smart and make cool decisions.
Some people are doers, they like to do stuff and get things done. They don't really care about the what and the why, they just want to fix the problem and make it go away.
Which one are you? I find that I'm more of a decider than a doer, and I'm not sure how I feel about it.
