The Meaning of Life

Back in my college days as a philosophy minor I remember spending an entire semester pouring over the question of the meaning of life. Never was I more engaged in an abstract question than this. Although theories abound, since unlike mathematics there is no quantifiable solution to the question, my classmates and I concluded that the answer is subjective, and it should be subjective. Each person must answer this question for themselves and likely revisit it often to check up on it. Perhaps the meaning of ones life evolves over time just as that individual grows and changes. Or perhaps as a person grows and changing the meaning of their life doesn't change, but they simply get closer to understanding what it has been all along. This seems reasonable to me and as close to a definition of what the meaning of life conclusively is.
For me personally, I do my best to revisit the question often and have found that many times the best progress I make on finding the answer is simply to rule out what doesn't matter.
I would advise you to spend some time meditating or just thoughtfully probing what the meaning of life means to you. Since it can seem like an overwhelming topic to wrap your brain around, I would also suggest starting by asking yourself what the meaning of life isn't to you. It seems much more approachable to begin thinking of a list for "The Meaning of Life is Not...".
On this list for me are things like haircuts, shoes, telephones, board meetings, anything I purchase in a store, and any object I own. This doesn't mean I don't partake in these items, but I don't spend much of my time engulfed in them or attached to them.
Cars are not the meaning of life, houses are not, and neither are jobs. You would never lay on your death bed and say "I'm so thankful that I had this life to live so I could buy that car. It was all worth it because of that". No. The meaning of life, the thing that makes you thankful for a nice long life lived, is much harder to put your finger on. This is why it requires and deserves some of your attention. Perhaps it takes a lifetime to discover what the meaning of life is, and maybe we never have a solid answer, but for me remaining mindful of what doesn't really matter helps me stay focused on the things that are of most value to my life. This mental exercise helps us to hone our sights on living the most meaningful life we are capable of in each moment we are fortunate enough to experience.
The world around is a question waiting to be answered, and it also holds the answers if only we listen closely.
