Marx, when talking about Louis Bonaparte, wrote "[People] make their own history, but they do not make it as they please; they do not make it under self-selected circumstances, but under circumstances existing already, given and transmitted from the past."

Obviously, the point Marx was making here is that, we are all products of the accumulation of history. We would not be here, in the way that we are, if it were not for the never-ending march of time, and with it, our history. However, the inverse is also true, in that, the actions we take now and today, forever forge a link in the chain of history. Do not be distracted by the grandiose notion of "history", however. History is not all things that find their way into the pages of a textbook. History is not just the epic of time, but it is also a personal and intimate story, of which you and your relations are the subject of.

So what of the links you forge? What of your familial bonds, your connections to friends, your entanglement with your greater community? Your legacy is your relations. To say nothing matters is to reject the notion that our actions in the material world have no impact on the development of ourselves and of our future selves, and the development of those we leave behind.

If you can reframe your point of view around this notion that your actions in the world lead to developments within others, then it's difficult to see how nothing matters. Every time you show up for someone who needs assistance, it matters. Every time you take up an activity, that gives back in some way, it matters. It can be difficult to read and hear about all the events of the time we live in. It can feel as though, nothing you do moves the needle. You must take that energy and direct it locally. Once you can see the results of your local actions, you will see a change in yourself and in how you feel about what "matters".
