If you are so worried of things that can be fixed that you can't fix them. Just remember we came to this world without refactions.

We teachers break our bodies to give you a shirt that you will wear in the future, to conferences, to presidential speeches, to autograph signings. That is up to you and if you can do that for at least in a little thank to us. Then thank you, thank you all.

Only yourself can critizice your ideas for you are the only one who knows where are they coming from and how they were born.
