Whether you call them lessons of life, facts of life or truths of life, there are certain universal truths of life that we generally cannot escape facing all our lives. Rather than fighting them, if we learn to accept them, we can unlock the secret of being happy all the time. Check out these 5 crucial truths of life you need to know to be happy.
不论你称之为“生活经验”、“生活事实”还是“生活真理”，反正生活中总有那么一些无法避免的公认道理。与其心生反感，还不如接受它们，解开快乐之谜，一直开开心心。请看下面有关快乐生活的5个至真道理。

1. What goes around, comes around
善有善报，恶有恶报

If you haven’t learnt this yet, you better start accepting the fact that your Karma is going to hit you back like a rock. ‘What goes around, comes around’ means if you do good, good things are going to happen to you. Understanding and appreciating the fact that hurting someone is only going to hurt you back in one form or the other, is the first secret to finding true happiness in life.
如果你还没有过这样的遭遇，最好现在开始就提高意识：因果报应犹如滚石。“善有善报、恶有恶报” 就是说，你若行善，善事也会临幸于你。所以，你要明白：伤害别人最终只会使自己在某种程度上受害。这样想的话，生活会简单快乐很多。

2. God helps those who help themselves
天助自助者

God, luck and fortune comes to those who help themselves. That’s right, folks. The idea of God helping people arises only after people work hard to get what they want. This is a truth that you need to know in life to be happy because we are all rewarded by God when we put in genuine hard work to achieve our goals – whether it is in the form of luck, fortune, happiness or love. So before wishing for something in your next prayer, we suggest you try and put in some of your own hard work first.
上帝、运气与财富只会降临那些自助的人。毋庸置疑。当你辛勤付出而有所获时，你便能领悟“天助自助者”的含义。因此，你应该快乐生活。毕竟，皇天不负苦心人，只要真正付出了，总有收获的一天——不论这种收获是好运、财富、幸福还是爱情。所以，与其不断祈祷许愿，还不如先试着把精力放在现在的辛勤耕耘上。

3. There are no free lunches in life
天上不会掉馅饼

You may have used this truth of life as an idiom in your conversation before but have you realized that this is a truth that you need to know? The real meaning behind this fact of life is that we should not expect anything from anyone without a cost. Whether that cost is in the form of effort, persistence, money, knowledge, skill or simply sheer hard work, is a different thing. You will find true happiness in life once you get rid of expectations.
可能你以前讲话时经常引用这句俗语，但你真正领悟了其中的道理吗？其实这句话是说，我们决不可对任何人抱有不劳而获的奢望。因为你总归要付出代价——努力、坚持、金钱、知识、技能或单纯的苦差事，事实便是如此。一旦你停止那样的奢望，生活便会开心很多。

4. Nothing is impossible
一切皆有可能

Of course, if you want to learn how to fly, we’d say that is impossible. But with genuine efforts, each and every one of us can achieve just about anything we desire! Are you wondering how this is linked with happiness? It’s simple. If you infuse the belief that you can achieve anything by channelizing your mind and energy with proper effort, you will surely succeed at the goals that you set. And we all know successful people are happier in life, don’t we? That’s the reason why this is a truth you need to know in life to be happy.
当然，如果你想要飞翔，那确实办不到。但只要真正付出，任何人都能实现期望的目标！你是不是纳闷这跟快乐有什么关系啊？很简单：如果你心怀信念，相信自己只要态度端正积极努力就能实现任何目标，那最后肯定能实现目标。而成功的人生活更快乐些，不是吗？所以这也算是快乐生活的真理之一。

5. You are unique and you should stop trying to be someone else
你是独一无二的，要做真实的自我

Do you think that that someone else in your workplace, office, college or school is way too cool or more attractive than you are? Remember friends that you are a unique individual and no other person on the face of this planet can be like you. This is a truth you need to know in life to be happy because you will be ruining your happiness and joy if you try to be like others. Make people like you for who you are, not for who you can be.
是不是觉得工作上或学校里总有人比你更优秀更有魅力？可是别忘了——你也是独一无二的，世界上再也没有跟你一模一样的另一个人了。如果你总希望跟别人一样，那反倒会亲手毁掉自己的幸福与快乐。试着让别人接受真实的你，而不是按别人的期望去生活，这样你才能快乐生活！
