How to practice video editing and such? on a low end pc with limited things.

So i downloaded davichi resolve thinking i could start a youtube channel but now im having 2nd thoughts. my ideas also seem hard or i just cant do it or too many people do it like gaming. i want to do youtube or something as ahobby but i struggle with almost everything and i feel liek i want to do something now and im juggling between many diffrent hobbys.

so what are some wyas to practice doing stuff or expressing creativity with the power of video editing? im not even sure what i could make becasue gaming was going to be my idea but idk or what i could play without the game crashing.
