how mutch is there to no?

Answer 1

By "no" do you mean "know"? The answer to this is simple...learn yourself, know yourself well and everything else you learn will fall into place. If you don't learn to know yourself, truly know yourself, then all the information or knowledge you pack into your head won't help you lead a contented life.
If you mean "no", there is only as much to "no" as you put into it. If you are saying "no" as a rejection, do you really mean "no" or do you mean "maybe". How much there is to "no" depends on what you put into it.
