Trust vs Surrender

It is easy to trust in God's plan when we're down, when we just don't know where else to turn, when life really hasn't gone 'to (our) plan', when things are horrific and awful and out of our control. But what about surrendering to God's plan when everything is ok? What about acknowledging God's control over our life in the good as well as the bad? What about asking what God would have us do, before doing it?
