All efforts will not be completely wasted. How much time and energy you pay is in the accumulation of future. Nothing in the world is fair, but the most fair time, you are lazy or hard, time will give results. It IS an eternal truth, which few people have been able to break through since the last century. However, if someone can go beyond its limits and give without expecting anything in return, then he will definitely get more.
