Passing on your skills is only a microscopic part of being a teacher, believe me we all go into teaching with our eyes closed! You need to be very I.T. literate, able to support students (or learners as they are now called, I'm a bit old fashioned - sorry!!), produce statistics for retention, achievement, ethnicity etc., be able to teach to your students' ability to learn - called learning styles, be able to indicate differentiation for each student's individual needs - and a ton of other stuff I won't bore you with now!:lol:, even teaching English and maths skills. Having a Certification of Education is only the start, you will also need qualifications for assessing students' practical assessments.
There is an enormous thrill in teaching, it can physically and emotionally enhausting, you are after all "on show" for many hours at a time - it is rather like being on stage and performing to a very critical audience. When you see your students doing what you can do, perhaps not as confidently at first, it is rather thrilling and some students just warm your heart and put a huge smile on your face when they get it right.
I wish you lots of luck and a very supportive mentor when you start.
