The nNinety percent of your daily activities do you do, are in the pilot automatic, i mean you don't think about that while are you doing i on autopilot.

Auto-pilot is a word commonly used in English, so you don't necessarily need to explain further

So many activities like walking, breathing, eating while you are watching a video, and many other,s are automatics activities.

Well my little friend, let me saytell you something really interesting.

InSince the time when we wasere living in the caverns, we had to hunt animals to survive, w. We had to pay attentions about to such things as the dangers which stallurked in the dark, and others things, so making those tasks required a lot of energy and attentions and o. Our brains hates to lose energy, w. We had to focus ion many things at once, and that required a looooot of energy.

The word "cave" fits better in this context than "cavern"

sSo our brains developed a system to makeperform thoese activities without loseing energy, is more, he got better our system to do those things at once and created a way to save power called "habits".

hHow does it works?

The meaning of this sentence is a little unclear, a better wording of this sentence could be, "Are habits something that we can build?"

Yeah, but we let's watch it in the furtherlearn more about it in future posts.

Punctuation should be inside the quotation marks.

I removed "I mean [...] doing" since autopilot is a very common term! People will know what you mean by it without having to explain it. (:

That's why we can perform many things at once and that require a looooot energy.

Habits are a more of behavioral tendency to do certain things regularly (like drinking coffee every morning, exercising six days a week, always letting laundry pile up, etc) while things like breathing are part of the autonomic nervous system. The brain plays a role in both, but in different ways, so I'm confused on what you're trying to say. ^^;
