Control

One of the hardest lessons I've learned is that some things you can control, and some things you can't. With that lesson came the realization that accepting what you can and cannot control will make you happier.

For example, I cannot control the attitude of people I deal with at my place of employment. However, I can control my attitude at said place. This has made my work life, as I said, happier.

Also, I cannot control who I have for family. I cannot control what they do, how they act, or who they interact with. What I can control is the opinions I hold of my family, and how I allow those opinions to affect the way I deal with them. Again, happier.

The biggest realization was that I cannot control who or when They™ (yes, I think in trademarks, since I don't want Them™ to be angry with me) tell me to kill. I can, however, control how I do it, where I do it, and what I do with the bodies afterwards.

And this has made me very happy, indeed.
