I am fairly active in local politics and somewhat less so in regional politics in my area and the best analogy that I can come up with to explain what it is like being involved is the following:
1) Find a large, solid brick or concrete wall.
2) Bash your head against the wall.
3) Repeat step 2 until blood is pouring from your eyes, ears, nose and mouth.
being involved in politics felt this good.
Hope that helped.
