I had a favorite quote growing up. I'm not sure if it's still my favorite today but it was
Peace cannot be kept by force; it can only be achieved by understanding. โ Albert Einstein
If I had to choose a quote today it would probably be the one that goes something like "What you do in life is ultimately insignificant but you should do it anyways"
What the 2nd quote means to me is that that isn't really a great plan or some special meaning to life. We just exist without any specific purpose. But you shouldn't let this fact bring you down.
Personally, I choose to believe that my existence is an improbability, much like winning the lottery. And this I want to enjoy my time alive as much as I can.
The quote also has a 2nd meaning to me which is that nothing we do really matters so I should just relax be more easy going.
I think I like the second quote more today because I think people today are too on edge all the time. I think a lot of people need to just chill. There's so many things wrong with the world but so many things are outside of our control. Sometimes it's good to just take a step back and relax.
