Our one big goal in life should be to love God. From a practical speaking point of view, I could just say that the big goal is to make heaven. Then in life, there are numerous other small goals, out of necessity or not, for us to accomplish. Here, whether we succeed or fail doesn't matter that much ~ only reaching that big goal is absolutely important, for it matters for all eternity! So be wise ~ focus on the big goal and set the small ones to help you achieve it.
