-Just because something doesn’t do what you planned it to do doesn’t mean it’s useless.
-Restlessness and discontent are the first necessities of progress.
-I have not failed. I’ve just found 10,000 ways that won’t work.
-To invent, you need a good imagination and a pile of junk.
-If we all did the things we are capable of doing, we would literally astound ourselves.
Thomas A. Edison
