There's a lot of difficult stuff on the internet. It's a weird feeling to turn it off. Like you're going to have some serious FOMO. But if you are strong enough to choose... It's actually very easy to focus on positive things in your environment or change your environment. When you try to take on the world's problems by yourself, it becomes like being stuck in mud.

That being said, pursue a passion that gives you a sense of ethical responsibility. If that can be done in fields that help the world get better, we will all love you for it. But you will never be as good at what you're doing without a serious obligation or passion. So in that regard, please sleep on this until there is no doubt it's what you want. We don't half assed people working on these issues, for obvious reasons.

There is still a lot of good around you. Have some hope, and move forward.
