I have a few theories about meaning and I'm still a bit lost between them.
Theory one: Human beings, with their free will introduce negative entropy into the Universe by inputting chaos (viewing the universe as a system, where everything is cause and effect, our free will, being free can be perceived as random information). So in a way, I think it might be possible that life is the Universe's solution to entropy. I'm not really sure on the physics on this one, so if anyone has a better understanding, feel free to correct me
Theory two: I had a shroom trip that consisted of a three-hour long loop, where I would try to figure out what the meaning of existence was, reach a conclusion, then deny it as too simple and start all over again. After the first hour I felt like the thought was stuck in my head forever as it was as if every minuted, the process repeated hundreds of times. This made me really think about searching for meaning, as it seemed as the error was even posing the question and making the error of searching for it. It reminds me of the retarded christian argument that since clocks are made by people who make clocks, the universe should have a creator, since everything is made by someone. The same way we conclude that life must have a meaning, since we're used to shit having a meaning, but this is an example of inductive reasoning (if you haven't seen any white horses it doesn't mean that white horses are non-existent).
Now that I saw the comics, posted in the comments, I think that it best describes my current approach to life's meaning. If anything I'm pretty certain there is no right way to do it, just a huge selection of options that are fun to play around with.
A nice read on the topic is Shroedinger's "What is life?". I haven't still finished it, but it looks reaally promising : ]
