Unfortunately, my post probably won't be very long or deeply philosophical or stuffs, but I will throw in my viewpoint anyway.
I don't think that life has any "meaning." We exist because we do. The universe was just fine before we were around, it is still fine while we are around, and it will be perfectly okay after we all have turned to cosmic dust.
With that said, I do my best to avoid being a negative influence on people and on society. So there's that.
