We're all products of our environment, and I suspect that strength of will - the feeling, "I'm going to be able to do whatever you put in front of me" - is honed in an environment where not everything is easy. Ironically, growing up in that environment, you don't have a sense of aggrievement or entitlement. You just have a sense of overcoming.
I'm not personally fearful, but I look out, and there are a number of things that concern me, and I'm hopeful that we can overcome them.
