You will be forgotten.
You, as an individual will be forgotten, in a few hundred years nobody will even remember your name or your existence. Your achievments will become meaningless. Now, this does not mean that your work won't be remembered, nobody remembers Shakespeare for the kind of person he was, but rather for the texts he wrote, but let's be real, you're not going to be even close to as important as Shakespeare. During your entire lifetime barely a million people will ever hear your name.
Here's my advice. You don't have to take it, I don't claim to know the truth, this is just what I think is right.
Don't waste time searching for the meaning of life, or your life. There is no meaning of life. Life just happened, make the best of it. And when I say, make the best of it, I mean, do whatever you like, don't try to appeal to others too much or just earn a lot of money, be yourself and be who you want to be. You've only got one chance, you've been given life with no goal, it's like survival minecraft. It's a sandbox, you can create whatever you want if you work hard enough for it, but at the end of the day, it doesn't really serve a purpose other than fill the time and bring you satisfaction. Be aware, you're not alone in this world, influence others, be influenced by them, learn, and teach. Don't be hesitant to try out new things, you might only have one chance. Be aware, that society is just a social construct and your rank in society doesn't mean anything in nature, you're not a stronger human being just because you are the boss of a big company. What's the purpose of lying if everything is meaningless? There is no purpose. Just say the thruth, stand straight for your beliefs. Make sure to do something that fullfills you, something that gives you the illusion of having a purpose.
Just because you don't have an assigned purpose doesn't mean you can't set goals, or that your life is worthless. The only wasted time is time you perceive as wasted. Be aware that we're all in the same boat, we all were kids once, we all grew up.
This is not coming from someone that is depressed or extremely sad, in fact, this is coming from the happiest person I know, myself. You might think that all of this sounds really depressing and if you live by those standards, you gotta be a really sad human being, but it is actually really liberating. You don't have to prove anything to anybody unless you choose to. You are aware that your mishaps are going to be forgotten and nothing you do will last forever. But you can still improve the lifes of others by being a good and sincere human being, by being a human being you can be proud of. You don't do things just because people will remember you fondly, you do things because you think they are the right thing to do. You have no power but yet you are incredibly powerful. You can observe and you can influence (some people may argue that observing is also a kind of influence, which I agree with)
I feel like this post has been somewhat of a mess but hey, watcha gonna do.
If you've read this to the end, thank you, and have a nice day :D
