It is a great post but in all of this a question kept popping up on my mind about life: how do you know what exactly to commit yourself into at a particular point in time. I have heard a saying that A Jack of all trade is master of none. Is it possible to be committed to several causes at the same time or one after the other, or perhaps it depends on individual capacity.
For me, I am a one way street, can't handle a lot at the same time.
