I think of myself as a member in a larger trend. If I think "my vote doesn't matter" and don't vote then people who think the most like me probably are also thinking the same. If we all do the same then suddenly our lack of voting does matter, and people like me won't get representation in government.

Then I suddenly remember voter turn out by age and realize that I basically just reinvented the age old problem of society being help back because the youth don't vote.
