We must lay one brick at a time, take one step at a time; we can be responsible only for the one action of the present moment. But we can beg for an increase of love in our hearts that will vitalize and transform all our individual actions, and know that God will take them and multiply them, as Jesus multiplied the loaves and fishes.
Whatever we do for the love of God benefits our souls and our lives in a way that ego-motivated actions never can. Whatever we do for the love of God is done with sincerity because it is not motivated by self-interest. We leave our concern for gain and loss, success and failure, in the hands of God. We stop considering ourselves as the sole cause of our actions and their results. Consequently, we become the instruments of a deep wisdom and love.
