It's a never-ending cycle, until you choose to let it end. We all get the choice to live in the world that exists as-is and let other people act on our behalf (or against us), or we can act on our own. Nothing is easy. Nothing is given.

We are burdened with the choice of action or inaction. When we act, there is a personal responsibility associated with it. When we don't act, we can easily point the blame at others because our personal investment is not there.

By no means do any of us individually have the entire burden resting on our individual shoulders (and we should never let ourselves feel that way). We do, however, get the choice to "be the change" we want to see in the world and act toward achieving the change that we want to see.

The challenge will always be that our change may conflict with another person or entity's version of change. Then we may be working to make a change in a world that does not want to be changed, or does not know that it wants to be changed.

... woah, I went on quite a rant, sorry if I went off-topic or missed the topic alltogether ...

Echoing some of the other comments, I agree: Always make sure that you're happy individually ... and when you decide that you want to change the world, know that you're not alone and find like-minded people to help support you (and support each other).
