What is the meaning of mind in your understanding?

I think our real mind is our pure thought that can record everything; all stories, all
events or even our thoughts every moment. It's called our sub-conscious.
We all have different data although we will face the same situation, our
mind will work and record in different way.     
so, if we do something again and again, it until becomes a deep habit, it will
be hard to edit or do the opposite thing, such as we always do good things, it is very hard to
do bad things like killing people or harm people.
Anyway, all human can practice our mind to approach the right way, just do a good thing,
then you will get the good thing definitely. What goes around, comes around.
