I want to make videos like you how do I start?
Do I need any video software? What do I need to  learn?

(Not going to copy you, or your style, I am just inspired by you and like the way you think.)
start with whatever you have and/or whatever you can obtain the easiest and/or cheapest. this is also important because it will be the easiest to use. I AM NOT JUST SAYING THIS. THIS IS VERY IMPORTANT. KEEP IT SIMPLE IF YOU ACTUALLY WANT TO START DOING THIS, and if you don't keep it simple i don't think you have a chance of succeeding. nothing ever worked for me until i started simple. start with like whatever is built into your computer, and if you don't have a computer maybe i can give you some suggestions. start ... simple .... use mario paint if that's all you have. you'd probably get projects done quicker than me
