You may feel like all your hard work doesn't count towards anything. You may think your hobbies are unproductive and a waste of time. But, your hobbies are completely valid as long as you enjoy them. Something doesn't have to be productive to be worthwhile. And although it may not always feel like it, your work is appreciated. Somewhere in the world, there are people who care about what you do and the effort you put into it. Just remember, the things you do, the hobbies you enjoy, and the work you create, it all matters.
It may feel like your voice isn't being heard, like you as an individual don't matter in the scope of the world. Just know this. You do matter as a person, and your voice matters. You being here does make a difference in the world.
