Two years is nothing. The first year is usually an unmitigated disaster/full time panic, as you learn to teach while you are teaching. Very few programs ever train people to teach before they are let loose. The second year you are just starting to gain your footing, barely doing better all the stuff that didn't work the first year. During that year you start to learn all the skills and tricks you keep in the back pocket to make things work. You are dealing with real live things, so they change and have millions of parameters that nobody has control over. Having a good roster of things you can pull out on the fly to adjust is crucial.
Maybe by the third year you have enough to become a good teacher.
However if you truly care about them and work hard because you care, and they know you care it all works out in the end.
