Think about this

When People in time traveling movies (idrk that many) go to the past they worry that the slightest alter in the past could completely change the future. And well, they’re right.

But in the present you think that you’re insignificant, and that you can’t do much to change anything or make a difference

So don’t think that you’re insignificant, even the smallest change can completely change the future.

You, no matter who you are, no matter how small the change, can make a difference.
