Mostly, there are two things to do before voting:
1) decide your position on multiple issues
2) think about how much the implementation of the system allows your positions to be communicated/counted (so some positions become more important because the system will allow them to have an effect)
both of these actions can be beneficial (and much so).
1 means thinking about life in society
2 means thinking about effective ways of agregating knowledge and preferences in a society
you could think of the elections as a holiday celebrating the fact that we live in a society, and inviting to think about it
