Bystander or participating?

In life things do happen around us and at times we also make things happen but its usually difficult to find many people who are willing to be part of a new thing especially when it comes to building. I have often found opportunities to get involved and participate in new initiatives which I believe I have put my best into to make it work.
Well, to some extent some have succeeded while some of these programmes have failed, but isn’t that what life is all about? You win some and you loose some. When you win you celebrate, and when you loose you find a way to deal with the failure and move on. Tell me would you rather be actively involved in a new initiative or be a bystander?
