Sorry - I just noticed that you're questions was more of: "If I were to go into teaching, what can I do to improve the process". My answer to you: have compassion. Create a sense of curiosity in your students. Look into Richard Feynman. If you can instill in them that deep sense of being incredibly curious and wanting to know more about the world (and it should come naturally - since the world and the universe is an incredibly interesting place!!!) - you will do well and you'll guide others towards a path that they'll always remember you for. I respect your sense of wanting to know how to improve this process, and I wish the best of luck to you if you decide to pursue it. If you do - you'll change a lot of lives, but I'm going to give you a heads up: it won't be the easiest path to take. You'll really struggle and I hope that you're persistent and you don't give up. In the end - it'll be a path that you'll definitely find a lot of meaning in, and you'll definitely more than change the world by doing it. All the best of luck to you my friend :)
