I see industries like food & retail doing well, perhaps kick-starting small parts of a national economy. That's one way an individual can contribute. We call it consumer confidence here, if I'm not mistaken. Buying small things like clothing, shoes, etc or food will have a positive impact if more people do it. Its a way an individual can contribute marginally. Then, if you look at things like buying new cars that also helps but as you say its a psychological game. If people are afraid their money will be taken unexpectedly they are going to hide it and keep it safe.
