If we encounter obstacles or conflicts, we may think "Why haven't I accomplish anything? I've been working on this for so long!". If these situation rises, we should contemplate on the causal ground: Have we used our minds properly during this matter? Have we made use of the opportunities we have, and gave our 100% effort on it? If we have, maybe the affinity for success has not come yet. Fret not, and continue ahead. If we have not, we shouldn't worry either. Put your faith in your effort and patience.
