All actions have consequences.
The most powerful action in a democracy is voting. Think about it. Every policy, program, or project undertaken within a democratic society originates from public officials within positions of power.
These people determine the quality of your life and your community. Their power comes from you and me voting them into public office. This group of people is essentially working for you as a citizen, and your way of showing satisfaction or dissatisfaction with their actions is through voting.
Hence, your choice to vote or not to vote is the most critical action with the most critical consequence you can take to effect change in a democratic setting.
But remember, your action to vote or stay at home have consequences.
The consequences of not voting during elections are dangerous.
When you do not vote, you essentially raise your hands in surrender to the choices of others. You give up control of your citizenship and accept whatever the politicians voted into power by others do to you, those you love, and your community.
Your job, life, healthcare (doctors, nurses, and hospitals), economy (currency power, stock exchange, and foreign direct investment), education (lecturers and schools), security (use of your police and military), transport infrastructures (road, rail, and waterways) and all other areas of your life within your society are dependent on the politicians voted into power.
If you do not vote, the consequences are so dangerous they can decide the direction of your life forever.
Your life is directly affected by the people in political office. Whether you like it or not, voting during elections is your best chance to ensure these people represent your interests. Staying at home and abstaining from elections is not an option for any responsible citizen of a democracy.
Remember: Elections have consequences far beyond the terms of the political office holder, and if you do not vote, you cannot complain.
