Some people say that the meaning of life is to serve god. Other people say that they try to have the most fun or help the most people they can. I believe that there are many meanings to life! It's so complicated to reduce an entire life to a single sentence. But I would say to have a fulfilling life, you must find things that you find really hard to do and go do them. The art of struggling through a problem is one of the most meaningful things you can do! If you do not know the meaning of life, or are trying to figure it out, you may find the meaning somewhere along the path of which you seek out the hardest things to do, and then do them. In seeking out difficulty you learn to appreciate what is really important, what matters to you. Why you care about certain things. Why don't you like someone using that mug in your kitchen? Why do you prefer cats to dogs? Why would you walk around the garden such a specific way everyday? Why do you wash your body before your hair?
Buddhist monks aim to reach nirvana by aiming to relinquish all ties to the physical world. They transcend the physical world.
In aiming to seek out pain and suffering in your mind and in the physical world you will find what is really important and you may just find your own version of nirvana within your self. Albeit with a lot less than you thought you needed to be happy.
