Life can be very difficult but also quite simple and what we do helps it swing one way or the other and I guess it's constantly moving between each.
Exerting some influence over it is a good way to move it to a more positive place but in doing so there's opportunity for failure. The thing is, that doing nothing at all, letting it slip by without that influence is a failure in itself. I think it's best to live life as well as we can, to create it as best we can...to do otherwise seems wasteful.
