Does parentheses work?

People say that watching TV or SNS is good, but I'm actually too lazy.

It's a hassle to do parentheses and such, but are there many people who have seen results?

And what specifically were the effects?

How much time should I spend per day?

How should I use it?

I find it too cumbersome and annoying, so I'm not sure if I'll be able to use it well if I buy it.

I was wondering if you could recommend something easy to use.
