I’ve often harbored the same thought myself. After many an hour attempting at, probing at, and dismissing solutions…I think I may have found one. The meaning of life is to give it a meaning.
Now that may sound like a rehash of the cliché, but I like to think differently. I believe we are here for a reason. Whether it be by a creator, or we simply just popped up out of nowhere, we ARE here. Resignation to life is almost a weakling’s way out. Life isnt easy, but its an interesting challenge. While it tends to drip with unsatisfactory times and misery, it does have a lot to offer an ENTJ. In our dreams we run things as we see fit anyway, right? Well, here is a reality with other crawling and breathing specimen, just waiting for the ENTJ to marshal! If life went exactly as I wanted it, I would become bored to death in a week. That link you posted had many different theories, some of which I’ve never heard. If so many a different theory stab at the prospect of life and its associated meaning, than in my mind, the only acceptable meaning is the one generated by the individual contemplating it. You are 99% more likely to agree and accept the conclusion you have reached yourself.
