most impotant method of study is teach other people

hi im ryusuke.

if you are doing it, you should do what i introduce from now.

that is teaching.

i mean you teach someone and you can gain knowledge.

teaching someone is output.

your brain is clean up by teaching someone.

so you build up your brain and you can have a lot of knowledge.
