@JustAGuy557 there is no end goal of life. Nor is there any simple answer to that questions, after all, how many philosphors have spent their own lives trying to conquer it? we all exist, and we all have an entire lifetime to leave our mark on the world and how we chose to do that may be as big or as small as we deem it to be, and that's probably the beauty of it all.
Life isn't a question to be answer, but literally something to live. We either make our mark or we don't. And 'our marks' aren't just going to be remember by those close to us, but anyone. How strange is it that you and I could possibly pass each other on the street and yet never should we know? We could live on two different countries, across states or even across hemispheres, and yet I know your humor by the marks you leave on the stories I write.
A gravestone is not the end or the final mark of our legacies, but rather the last checkpoint, if I had to sum it up. People are going to come and go, and maybe in 500 years our life will be forgotten, but will our words? Will our stories? The art we leave behind in all forms? The books we read, the air we smell, the home we live in. People won't forget those.
We can do everything or not, but the choice will always be ours. And it's never just to die, but to just pass on to the next. Not everyone gets the limelight forever, and whether we like it or not, at time we must pass the light and torches on to the children in order to give them the joys of the life that we may never get.
Life is really just about living. And it's not someone else's decision, but our own. Because you, against all odds, are alive.
